They scheduled interview 2 months after I applied, they told me I'll be having 4 rounds of which they scheduled the first 2 on a single day, after completing the first two rounds there was no communication for further rounds for almost 3weeks, so I followed up by calling them and mailing and I had mentioned that I'm holding an offer and joining date is in about 10 days, they hardly cared to respond. So I assumed I was rejected and after a week I got a call asking me when I'll be free for last two rounds... I gave them a date and they mentioned my first two rounds have gone well enough. And after this while I was waiting for scheduling of next two rounds they sent a mail saying the position is closed.
