I got an email today inviting me for a first round interview sometime next week. The time frame is too close and I don't feel I am well prepared. I would be considered an "experienced hire" and work schedule is also hectic on the days suggested. Am I at risk of losing out on another interview if I ask them to reschedule and state my reason? The email I was sent also mentioned that in case I can't make it, they would do their best to get me in for the next cycle. Also, is it a bad idea to ask which verticle I they are considering me for in order to focus my prep? or is it SOP to go through the interview process and they determine which role you're best suited for?
