Very casual and comfortable, the interviewer was extremely friendly as well. Felt as if we were having a conversation, interviewer was very interested in why I thought my university program was fit for QA. (Haven't received response from company yet, disregard the answer to "Did you get an offer?" below).

Two stage interview. One with the HR and the other one with the respective team. Second stage involves analytical & situational questions around medium difficulty. Results are shared in ~2weeks time period.
