Despite a warning from a current employee about how most teams in this company are not great for women, I applied to Just Eat because I was actively pursuing opportunities in Go development. I looked up the hiring manager's profile on LinkedIn, and I thought we would get on well as we seemed aligned in our motivations and professional mindset. The interview seemed to go well. When I asked for an update, one piece of feedback I received was that I seemed confused about parallelism and concurrency, and that they would still proceed with my application. However, the next time Just Eat contacted me was when they asked for feedback about the interview process, which left me quite confused. Regarding the confusion between parallelism and concurrency, when I was asked if I had used Go’s concurrency features, I mentioned that I had fixed some race conditions and enabled many tests which used channels to run correctly with t.Parallel(). Looking back, perhaps I should have specified that t.Parallel() marks a test for concurrent execution, and they will run in parallel depending on available resources, but I thought a Go advocate would understand this implicitly. One thing to note is that they seem to evaluate CVs largely based on keywords, so despite having described that you've done something in detail, if the keywords are not explicitly included, that experience will be overlooked.
