I applied online. Got a call with their head recruiter same day or day after but it was very quick. After that was a hackerrank with 6 problems and 1 multiple choice. The problems were not that difficult if you're pretty familiar with the STL, but you do have to move pretty quickly. I think I was allowed 90 minutes and I used almost all of it. Second round was with one of the developers on the team. Again, the problem here was not difficult. I had to fix a memory leak and a list of objects being sorted in the wrong order. They're also looking for if you can tell why the memory leak occurred. I was able to fix the code but couldn't give exact reasons as to why the leak occurred so I think I got dinged here and didn't get to move on to the next stage.

Everything out of them is automated, no hello and a virtual handshake, just "here's a HackerRank test, eat it." An application has no idea if they're dealing with a person on the other end or if they're just getting automated emails. The HackerRank is programming challenges. Most of the questions are straightforward data manipulation. There was one tricky question around bit flipping. The test is time intensive and even if you are a strong programmer, you really need all 90 minutes. After spending a hour and a half of my time, I received a rejection email with no real explanation behind their decision.

First you get a HackerRank, then a phone call with the hiring manager, then a live coding test, and finally an onsite interview. The HackerRank has some basic Leetcode Easy/Medium level difficulty questions. The live coding test consists of debugging a program in C++ and then a brainteaser question. I did not receive an onsite interview. The hiring manager is very nice and very prompt with responses. The Engineer in charge of the live coding test was very nice and helpful as well. Unfortunately, I was not given an onsite interview because I lacked familiarity with C++.
