What I Have Learned From Organizing Remote Internship

by Ivan Nemytchenko

In this talk, Ivan Nemytchenko shares his insights gained from organizing a remote internship for junior Ruby developers. Over nearly two months, he explored various aspects of continuous integration and applied this learning through practical teaching methods. The main themes he discusses include the importance of mentorship, real projects for development experience, and the significance of structured learning in coding.

Key Points:

Background: Nemytchenko has been in the Ruby development scene since 2006 and discusses his journey from a junior developer to a mentor.
Internship Motivation: He organized the internship to create a platform for juniors to gain practical experience while he developed prototypes for his ideas. The structure involved keeping technology simple, focusing on Ruby on Rails.
Application Process: The popularity of the internship led to a flood of applicants, necessitating a filtering process through an aptitude test that assessed coding skills through practical assignments.
Performance Evaluation: Candidates worked through a three-part test, which intentionally included challenges that allowed them to recognize flaws in their code and decision-making. This process was crucial for their learning experience.
Outcome of Projects: Some successful projects from the internship included a Ruby on Rails quiz and a platform automation tool created by the interns themselves. Their work included creating tasks automatically based on code changes.
Challenges Encountered: Nemytchenko realized that the scale of the internship was larger than anticipated, leading to roles that caused him burnout due to the demands of mentoring and managing multiple teams.
Lessons Learned: He emphasized the need for better filtering of applicants and outlined the importance of real project experience and teamwork in junior developers' growth.
Future Considerations: Looking forward, he aims to refine the internship structure and mentor guidelines while continuing to focus on collaborative problem-solving tasks for junior developers.

Conclusion:

Nemytchenko concludes with reflections on how mentorship, structured tasks, and collaborative projects are vital for the growth of junior developers. He advocates for practical learning and suggests that pairing juniors with seniors can foster an environment of shared growth and responsibility in the tech community. This experience has encouraged him to potentially repeat the internship program, with enhanced criteria and clearer roles for all participants.

00:00:04.210 Our next speaker is Ivan Nemytchenko. He's from Russia, but right now he is living in Serbia. He has been a Ruby enthusiast since 2006 and a speaker since 2010. He has led something at GitLab since 2016. A little bird told me that he wants to brew 50 liters of mulled wine for an after-party. What's the story? So, let's welcome him on stage and enjoy!

00:00:47.899 Thank you. That's true. Today, I'll be talking about my experience of organizing a remote internship for junior Ruby developers. This happened a year ago, so this is not related to my work at GitLab. Instead, I spent time actually exploring development and its possibilities and explaining it to other people.

00:01:07.729 I spent almost two months exploring the possibilities of GitHub Continuous Integration, and I have a question for you: please raise your hands if you're using CI systems. Thank you! It’s actually hard to understand who is and who isn't using CI, so yeah, I know that's a shame. But let's get started!

00:01:51.350 I got my first paid job as a programmer in 2002. I switched to Ruby in 2006, and by 2008 my projects had grown larger. I found another person with similar experience, and we started to work together on a project. This context is important for the story I’ll share.

00:02:29.310 Later, we found two juniors and taught them everything we knew. We started to work together. Eventually, our small company was merged into a startup, and one day two students appeared in our office. They needed a project to finish for university and needed documentation proving they completed a project at a real company.

00:03:00.959 We gave them tasks, they completed them, and we provided them with the necessary paperwork. They then disappeared, but later, they graduated from university and came back to me, expressing their love for Ruby. They wanted me to continue teaching them and help them become Ruby on Rails developers.

00:03:31.799 Since I had been working at a startup, I had learned quite a bit about how startups function. I had many ideas I wanted to develop, and I saw it as a good opportunity to pass some of my ideas to these juniors for implementation while I taught them how to build Ruby on Rails applications.

00:04:01.650 Two months later, they built a prototype for me. I presented my startup at some meetups. However, I realized that building a prototype and writing code is not enough to become a real startup. Later, I joined another company where those two guys also became developers.

00:04:41.590 I eventually quit that job and returned to freelancing. It was during this time that I realized I had missed out on a lot of learning. My code quality was subpar; my business logic was tightly coupled with the framework. I began reading extensively, watching videos from conferences on topics like SOLID principles, design patterns, and architecture.

00:05:21.250 I had a couple of projects where I applied newfound knowledge, and I even gave talks, like 'Stop Being a Rails Developer' and 'From Rails Way to Modular Architecture.' I created a website called railsfarce.com. The first lesson I want to share is this: don't be the best student in your class. If you're the best student without a mentor providing feedback, you might spend a long time trying to improve.

00:05:58.720 Now, let me tell you about the internship, which happened almost exactly a year ago. I was working part-time on a freelance project and looking for ways to invest my spare time in something interesting and potentially useful. I wanted to find a couple of developers to create prototypes for my applications while teaching them at the same time.

00:06:55.160 What they would gain from the internship is important: they would have a project to add to their portfolio, experience developing from idea to production, and insights into teamwork and remote work. The technology stacks were kept simple, mainly focused on Ruby on Rails, and I requested a commitment of at least 20 hours per week.

00:07:43.110 I wrote a blog post about this, which accidentally became very popular. In the first couple of days, I received about 20 applications, and within a week, around 40 applications. Initially, I was excited that the internship was gaining traction, but soon I became overwhelmed by the volume of applicants.

00:08:28.200 I decided I would need to filter the applicants, so I started to think of tests to sort through the candidates. While working on this, I received approximately 60 applications. This led me to another idea: perhaps there was enough demand that I could turn the internship into something scalable.

00:09:01.920 Instead of rejecting anyone outright, I made the aptitude test. If applicants could finish it, they could work on a project. Let me show you how the test was structured. The first part was straightforward; they needed to create a simple web application that included registration, a product list, and the ability to create and view products.

00:10:13.800 Most interns could accomplish this in a day or two. After someone completed the first part, I would send them the second part, which included more complex requirements, including handling three different types of users, each with unique registration forms and validation rules.

00:10:53.220 For the third part, I introduced the ability to purchase a product via an external API. The logic for this purchase was somewhat complicated—if done naively, the code would be laden with nested if statements. I did no code reviews between stages.

00:11:21.250 The end result was intentionally poor code, as I wanted the interns to write the worst code they could manage. My intention was to prompt them to think critically about their decisions. Different approaches to user types could arise—like single table inheritance (STI) or multiple models.

00:12:05.069 My goal was to make them aware of the challenges that come from their decisions. Ultimately, they experienced not only the mistakes but also the consequent pains of poorly structured code. I observed common mistakes, like ignoring abstraction levels or conflating external API handling with business logic.

00:12:53.540 After this test, I organized Hangout calls to review the code of the first batch of interns that completed the tasks. We went through every project step, analyzing the decisions made, discussing what was good or bad about each choice.

00:13:15.690 I then delivered short lectures about patterns that could help solve many of the issues they faced. Following that, we had a refactoring session, where they worked on each other's code, and afterwards we progressed to the project phase.

00:14:23.430 One of the first successful projects was the Ruby on Rails quiz, completed quickly by one of the teams, and it gained traction. Another exciting project was that the interns developed the platform for the internship themselves, including automating task delivery.

00:14:52.620 Whenever someone created a tag in a repository, they would receive the next task automatically, and another team implemented a dashboard for easy project and tag browsing. One of the most ambitious projects was intended as a standalone open-source alternative to New Relic.

00:15:27.290 The project was led by interns with two external mentors, myself included. This project was ambitious and indeed challenging for the interns. I also faced logistical issues; with around 16 interns eager to work on projects, I only had those two mentors for guidance, which placed a heavier load on the remaining mentors.

00:16:10.870 I realized that I was treating the internship as less significant than it actually was. While I had anticipated a straightforward project, the reality was complicated due to the inexperience of some junior developers. I found myself playing three roles: product owner, project manager, and code mentor, which eventually led to burnout.

00:17:06.720 Moving forward, I wish to filter applicants better and manage the expectations more realistically. Even with only two teams, managing those teams was challenging. Having two more could help mitigate some of the management issues encountered during the internship.

00:17:53.860 The aptitude test was a resounding success in terms of allowing interns to understand what they needed to improve upon. I received emails from those who passed the test stating that they were able to find good jobs as a result. Reflecting on this year, I would consider running a similar program again.

00:18:41.600 Now, let’s discuss the needs of junior developers. Primarily, they need authentic projects to work on. A real project provides context, with an underlying business reason for tasks—this is critical for development.

00:19:39.130 Additionally, they need projects that they can showcase in their portfolio, experiences that cover the entire development cycle, and the opportunity to work as part of a team. Many beginners lack these collaborative experiences.

00:20:19.370 Learning can take place at conferences, which can be a gap for developers in transition. I call this exploratory learning. You expose yourself to a variety of new skills and information, asking yourself where to direct your efforts.

00:21:01.550 If you dedicate time to focus on one skill, you can improve in that area, but you may lose sight of others. While reading books or taking online courses can build a solid understanding of theory, practical application often requires hands-on experience and feedback.

00:22:03.490 Beginners often undertake pet projects, which develop practical skills. However, without mentorship and feedback, they may miss out significantly on crucial constructive criticism necessary for growth.

00:22:52.150 Many beginners mistakenly believe that reading books and watching courses will automatically qualify them for positions, ideally when they have absorbed enough information. In reality, effective learning is incremental; starting with something practical yields better opportunities.

00:23:38.750 By growing from simple tasks such as scraping web pages, beginners can improve gradually, making themselves increasingly valuable. They can also contribute to open-source projects, where they engage with like-minded developers in meaningful, impactful ways.

00:24:35.160 Senior developers often find themselves busy with numerous tasks—research, routine features, and missing functionality in open-source projects. They often lack time to contribute to the very projects they wish to see improved.

00:25:44.080 However, these responsibilities align precisely with the needs of junior developers. If seniors delegate certain tasks to juniors, they can help foster a collaborative environment where everyone learns and grows.

00:26:42.720 The ideal situation would involve juniors sharing the senior mindset, cultivating growth and responsibility. This mindset is formed through individual project experiences and learning from mistakes made at various stages.

00:27:55.230 I propose turning this experience into a set of well-defined tasks for juniors, mirroring the tasks seen in the initial internships. This could be beneficial for companies that could leverage this collaborative synergy, orchestrating skill development and project results.

00:29:01.750 If I decide to run this internship again, I will implement better testing methods to assess candidates, not only for juniors but also for mentors. I plan to clarify the guidelines that mentors need to follow and to continue creating tasks that channel valuable mentor experiences into developmental opportunities for the interns.

00:30:30.780 Thank you for your time. I still have some stickers left, so please come and ask for them. I'd love to engage with anyone related to teaching or mentoring newcomers in technology.

00:31:05.750 Thank you!
