Got interview schedule - nobody showed up. Then I reported this to HR and got it re-scheduled. On the interview there were 2 technical problems array-related. Got an offer, which they sent not directly, but through my co-op manager. Only duration and wage were mentioned there. When I asked for more details (full offer document) - they refused. I declined it (again through my coop coordinator), and then they messaged on my email that they regret to say that they refused. Very weird process.
