Introductive call with the HR employee, lasting about half an hour, in which I introduced myself. Further video call with the technical department (lasting about 1 hour). They mainly asked technical questions, but also life details.

Got this interview at a career fair on campus. Two interviews with hiring manager. First interview was just screening interview, so pretty quick and basic. Reviewed resume and asked questions based on that, also gauged interests and compatibility with teams that are hiring at the company. Second round was longer, around an hour or so. This interview consisted of behavioral questions, more questions on resume, problem-solving conceptual/technical questions.
