Hiring process was fine for the first 3 rounds, they called me for a fourth round after 1.5 months and it felt like they were interviewing to reject me. The HR person was very unprofessional, had to send multiple follow up emails after each interview. No response after last round, been 2 months so figured out that there was no offer. Even though if there was an offer, would have declined it after experiencing team’s unprofessional behavior.
