Applied around end of May, got interview email mid-June. During my first round ZOOM interview, the interviewer did not show up at all. After 15 minutes past the starting time I was still in the ZOOM meeting waiting while not getting notices. Thus I emailed the HR and she said the interviewer got COVID that morning and wasn't able to do the interview. and rescheduled it to the same time slot the next week. The interview was not hard, some basic behavioral questions and simple technical questions.
