I applied through a job portal. I received a call from the company asking me to attend the interview rounds. I was the only candidate present that day. The HR arrived after making me wait for 1 hour and took my interview. It lasted for 45 minutes. Then I was made to wait for another half hour and the second round of interview took place. It was an assignment based test to check my skills. This round lasted for 2.5 hours. I was asked to leave for the day. Next day I received a call from the HR asking me to come over and attend a F2F round. I went and was again made to wait for 1 hour. The interview took place and the interviewer seemed unhappy and disinterested with all my answers despite all being right. After the interview, they made me wait for 1 hour and was asked to leave for the day. It's been 2 weeks since then and I still haven't received any call from the company. I contacted the HR and sent mails to follow up but received no response.
