Your standard software engineer interview. Quick phone screen interview, then an interview with a hiring manager, and finally a 3 round panel interview.
The first round of the panel interview I was asked to look at a node package that I'd never used before, and see if I could quickly learn it in about 30 minutes. It was the first time I've ever had an interview like this, and while I understand the idea they were trying to go for, in pratice it felt very awkward. The feeling of someone watch you try to understand something new while two people sit there silently judging you isn't very fun or very representative of how you would learn something in reality.
The second round was just your basic coding interview question where you were asked to code a solution to a problem. The problem was pretty easy, and the two interviewers seem pretty nice and helpful.
The final round was just a conversation about the company and an opportunity to ask more questions, no coding.
Overall the interview process was fine, but the reason I marked this a negative experience is because after the final interview I was just ghosted by Xometry. I reach out after a week of not hearing anything, and was told that they would have a decision the following Monday or Tuesday. It's been a week past that date and still zero update, zero communication. It's unacceptable to just ghost people after they have invested that much time into your interview process. If you aren't interested in hiring them, then they very bare minimum is to at least email them with a rejection email. Xometry failed to do even the bare minimum.
