When I got the initial request to do an interview, I submitted my availability that same day. They let me know that they would reach out within 24 hours to schedule a call. I replied back to the email saying that it was submitted. Three days went by, and I followed up. Nothing again for a week. I finally got an invite to a call for the same day, and took the interview.
A few days after the call, I got an email saying that they wanted to move on to the next round, to submit my availability, and they would be in touch within 24hrs. I submitted my availability, replied to their email, and waited. After two weeks, I gave up on trying. Didn't want to work for a company that strings interviewees along like this.
