First-hand accounts from people who interviewed at League.
Software Engineer
I had a technical interview with two engineers, but they didn't seem very knowledgeable about application security and tools like SAST/SCA. It wasn't a great experience because I felt I wasn't selected despite answering all their questions correctly, due to their lack of knowledge. When the Director of Talent told me the result, I asked for specific feedback from the last interview or the reason I wasn't selected. I also offered to provide feedback on the interview, but I didn't hear back.
- Can you tell me about a past project you worked on?
- What key aspects do you consider when reviewing code?
Senior Software Engineer
The interview process was surprisingly enjoyable and lasted about two weeks, consisting of five stages. It began with a recruiter screen, followed by a technical take-home challenge reviewed by two engineers, and then an architecture take-home challenge with its review. The process also included a cross-functional interview and an executive interview. There was a brief communication gap with the talent team after some follow-ups, which seemed to be due to someone being on vacation. Fortunately, an internal contact helped get things back on track. Since the role was frontend-focused, much of the discussion centered on frontend technologies, though my full-stack experience was also relevant. Standard questions about my technical background and desired impact were asked, along with getting to know the interviewers. The overall vibe was great, leading me to accept their offer.
- The technical challenge involved creating a small photo application using a provided API and letting me choose the frontend technologies.
- For the architecture challenge, I had to design a system for a component responsible for handling uploads.
Software Engineer
So I interviewed for a Software Engineer role at League and did all the rounds, like technical, architecture, and final discussions. It was a pretty disappointing hiring process even though communication was clear and I participated fully. The interviewers were nice and the process was structured, but honestly, it was disappointing in the end. After all those rounds and good talks, they told me at the last minute that they thought I wasn't a fit. Then, the job posting disappeared. It felt like a waste of my time and effort because it seemed like their decision was more about internal changes and budget issues rather than my actual fit or performance. Companies should really sort out leveling and pay early on to avoid this kind of miscalibration so late in the game. I hope League gets better at being transparent and coordinating internally so candidates don't go through the whole process only to find out the role isn't even available anymore. Pros: Interviewers were respectful, scheduling was clear. Cons: Leveling was figured out super late, the position got removed after I finished all rounds, I put in a lot of time for a result based on internal shifts, and the hiring and compensation teams weren't on the same page.
