Interviewed by a coop student and worker. Asked general questions about projects and why you chose specific tech stacks. Also asked about work at previous jobs and specific implementation details. Also generic behavioural questions ("tell me about yourself, etc.").

Received interview for 4-month position in Feb 2020. The interviewers were also current students working at that time. There were 2 rounds of interviews (though the 2nd round appeared to be optional because I got the offer despite skipping the 2nd).
