Most companies I have applied to have two to three rounds of interviews happening on one or two days. This company, on the other hand, has four rounds, all on separate days. These people are not only indecisive, they will literally ghost you if you don't get the job. If I spent time and energy on a job posting, I expect the company I interviewed with to at least let me know if I didn't get the job. It takes three minutes, at most, to send a rejection email. Candidates, don't waste your time with this company.
