Call with external recruiter, then call with internal recruiter, then call with hiring manager and one of their direct reports, then 4 hours of multi-round in-person interviews. Most of the interviews were not particularly technical. The in-person interviews were with two people at a time, and there were some typical STAR-type questions. The last part of the process was being taken about the lab and asked questions about the equipment to see what I knew. Unfortunately, even after I spent several hours and took time off from my current job to interview at Seagate, they didn't have the professionalism to call or email me to tell me the result of the interview. The only information I got was when, after over 2 months, the online job application status changed to "process completed", and they reposted the position. Rejections are fine. Silence isn't.

Very unprofessional…! I applied online. The process took 2 months in total. 3 steps. 40 min preliminary interview with the hiring manager. Then a technical presentation based on my research and 3 panel interviews. Finally one hour interview with the hiring manager again. Then I was told that I will be contacted within a week. But they didn’t care to inform. I sent follow up emails twice. One after 15 days, another after 21 day. They never replied. I was totally ghosted. Such an unprofessional attitude from someone at a director level is just unacceptable.
