After talking with HR, had my technical round with a lady from OR team. She clearly didn't know what she wanted and was not prepared at all. She started with "let's say we want to assign trucks to different loads. Now ask me your questions about the assumptions". I wanted to make her impressed, so I asked like 1000 questions (e.g. is there a deadline for delivering each load?, is there pickup and dropoff?, and 10s more) and she was saying Yes to every single assumption I was explaining. In many cases, those assumptions were kind of conflicting, and still, she was saying Yes! Then she told me now formulate this problem. Excuse me? This model would have had at least 20 sets of constraints and it was way more complex than TSPPDTW. How do you expect me to model in like 10 minutes? I modeled a very easier version of the problem, at the end. And after the modeling, she asked me some other vague questions about modeling and some other ML questions. Got the rejection email the next day. What a waste of time!
