Applied on college's career website. The HR scheduled two initial rounds of on-campus interviews which were a little bit different from the common in-person interviews. Instead of doing white boarding, they made us code on our laptop while they sat aside and looked. I cleared the on-campus round and interviewed at their HQ in SF. The onsite round consisted of two similar interviews in which you coded on a PC with the interviewers sitting beside you. The interviewers were really nice and helpful and Square is awesome as a company. They have amazing office views and canteens. My experience after the interview was extremely unfortunate. They contacted me shortly after the interview and wanted to schedule a phone call to discuss next steps. However when the scheduled time arrived, they canceled it and said they needed to finalize something. And a week later they told me I did a good job but they were short of openings and asked me to wait. We sent email back and forth for about like two months and they failed to place me into any of their offices. It was really unfortunate. But I will still apply next year for full time role.
