The recruiter will give you a laundry list of all the reasons Rearc is an engineer's dream to work for. After an initial conversation with HR, they'll provide an exercise that should take 4 hours" to complete (according to them). They explain doing "everything in the exercise is not a guarantee that you will pass". I did everything, it took me about 4 work days total work days to complete. The exercise uses a few things like nodejs that I needed to take some time to better understand before working on the solution. I hit all the deliverables and everything was automated and carefully documented. I made the mistake of thinking they would give me the courtesy of a conversation to discuss what I did and why if I did everything the exercise asked for. Instead of that, they just gave feedback that wasn't accurate. Referred to technology and configurations that weren't part of my solution and then added a few comments like "They obviously don't understand the benefits of x technology", and "most of this is manual" when all of it was automated. I got the impression they either didn't bother to look at my solution carefully enough to understand how it worked or they didn't bother to write accurate feedback. I found it to be a little rude to ask for a candidate to spend time to be hired for them if they aren't willing to match the candidate's effort. I wish I would have known they weren't going to be as thoughtful and detail-oriented as I was before I spent any time at all with their hiring process.
