Connected interview questions

I applied online and they replied within 3 days. Firstly, they told me to go through the Hackerrank coding challenge. There were 3 questions (2 coding and 1 multiple choice). I passed the test and then they called me for onsite technical interview. Firstly, 2 developers showed me office and asked me for drinks etc. They told me about their work culture, meetings, hackathons etc. They make you feel so comfortable.Then we went in a meeting room where we were joined by one manager also. So, it started with my projects etc etc followed by programming questions on board.
