Interviewed with PI over the phone. Mostly talked about my experiences in bioinformatics and he asked some questions about linear algebra. Got accepted after the call without a second round of interview.

They had face to face interview which is good that all the team members were getting together. People are nice and kind, but they are very busy so try to be there asap. It may take sometime to find the location and parking your car, so be prepared to go earlier so you have enough time.
