Automated email offers you a 90 minute HackerRank OA. At no point are you offered to talk to a real person. Look at the sheer number of interviews reported on Glassdoor — even if you’re not in software, your interview is automated. They’ll let anyone waste their time on the OA and they will most likely reject you with an automated no-reply email.

2 OAs which test in depth concepts of C++ and LC type questions with only one test case for each. After passing both OAs phone call for 30 minutes interview. Interviewer had an omniscient god like feeling despite being conceptually incorrect. I don't know why they take interviews when the interviewer won't even listen to you and they are gonna reject even if you code the solution. Don't waste your time.
