Veeco Instruments interview questions

Email back and forth with Recruiter, then a phone interview, then a face to face interview with owner because recruiter was out sick, then face to face with recruiter who would be my colleague, then I was given the job offer

Phone interview with HR, and then another phone interview with the hiring manager (HM) a week later. Don't bother applying if you need a sponsor, and take my word for it. I didn't get a single reply back when I needed a sponsor, but right after I put a sentence about not needing a sponsor in the resume, bam, I was contacted two hours later after the submission. My experience with the HR recruiter here was just horrible. After the phone interview with her, I scheduled a morning interview with the HM through her several days before. I told my current boss that I will come in late, just to take this interview seriously. On the day of the interview, no one called me at the designated time, so I called her after 10 minutes. I don't exactly know how they schedule things, but she said something about she scheduled it, but it's not on his calendar. She asked me If I can do it that afternoon. So I said yes. About an hour before the changed time, she called and told me that HM cannot make it, and asked if I can do it tomorrow. Basically, I wasted my hours, and the worst part is she never said sorry. She wasn't rude or anything but I definitely deserved an apology. Besides that experience, everything else was just normal.
