Coding Technical
I had my first technical interview. I got a hackerrank link with 3 questions. Two were coding questions, and one was a code review. They weren't too hard, and I found the code review part pretty simple. I'm waiting to hear back.

Coding Technical
I applied for a C++ position and heard back from the recruiter via email. They sent over some standard info and a coding test with a two-week deadline. Looking back, the amount of info might have been a hint about their process. I took the coding test, and managed to get one question totally right, another one was partly correct, and then there was a question that felt like a code review. The one I messed up had way too much confusing information, making it unclear what was really needed. I'm guessing they expect perfect scores since I got rejected.

- Question about minimum grouping and ids. (filled with fluff)

Technical Coding System Design Behavioral
The process involved a phone call, followed by two onsite interviews. I'm not sure I'd recommend applying. Either they aren't hiring, or their hiring bar is set impossibly high, possibly higher than their current engineers could meet. The questions they asked about algorithms and solutions make me think this. They said they liked me and that I provided optimal solutions to every question, yet they still passed on me, citing communication issues. To make things worse, they botched one of the interviews – it was supposed to be non-technical, but all interviews were technical, and they seemed to use that against me.
