i got to contacted by email, with a link to book a meeting in their office. Next day i show up and it started with a manager explaining about the company to me and other 9 people, then after 30 minutes we spoke 1 on 1 but it was not an interview

The interview was pretty laid back and calm. The interview felt pretty informal and conversational. I was asked the basic behavioral questions like "tell me about yourself" and "why do you want this opportunity". There were not any "gotcha" questions during my interview. The interview was two rounds (one phone call and one video chat).
