Quantexa Design Engineer interview questions

Never seen a more disgusting example of ghosting, when I told other recruiters even them were shocked. their recruiter sent a mail to arrange a call, then 2 weeks later on the day of the call asked a confirmation, I immediately said that I was ready for the call only for him to ghost. I then sent another message to ask why the call didn't happen only to receive no answer. says a lot about this place.
