Coding Challenge, 15 minute phone screen, 2 technical phone interviews, and a final onsite. While the engineers were great to talk to, and the culture seems great, but my recruiter lacked a lot of communication. Can't reveal more information, but it felt like they were telling me lies to stall for time.

I received an online coding challenge via HackerRank. I spent a significant effort making sure it passed the edge cases. I went further, explained the code in comments and refactored it as well. No response. Not even a rejection. I sent a couple follow up emails and still nothing. Do not waste your time taking this challenge. It's not trivial and they don't even have the courtesy to respond. Spend your time studying or anything else productive.
