Totally unprofessional. After one of my rounds, I was sent the wrong information. Then there was silence for a long time. When I followed up, I was told that information was meant for another candidate.

After that, I was told they would get back to me, which they didn't. When I followed up again, they said another person had planned to call me and they would follow up. Again, it didn't happen.

After following up a third time, they just didn't reply. So, in Glassdoor terms, I didn't get an offer, but in fact, they just seemed to lose my application.

Also, my interviewer was combative. It was discussed that specific technology was not required for the job. The interviewer then grilled me on that tech when I told him I didn't have experience with it.

HackerRank random questions. Unfortunately, it picked a question with an obtuse 1000-word description. Too much time was spent trying to process the description and figure out which parts were irrelevant while someone watched me, making for poor execution.
