Long process and very unprofessional and disrespectful. Went through multiple interviews which took a very long time and was exhausting. Entire process took 4 months! First interview was with HR to talk about the role. The second interview was with one of the manager and went through resume and some technical questions. After that, I was told to do a take-home test with a few questions.The third interview was with a two sr engineers where we went through technical questions. The fourth interview was with another manager who had a different background in engineering. After that I had virtual onsite which also required to create a presentation with a panel. The virtual on-site had 7 interviews with different people across the organization which spanned over 2 days. After that, I did not receive any feedback for three weeks because the hiring manager was on vacation. After the on-site virtual which I received feedback went well, I was asked for 3 references. All three of my references were contacted but the hiring manager only called one. I talked with my other references and they said they were contacted to schedule a meeting but after responding on available times, they were not contacted again which was very rude. I had to keep asking the HR contact on any feedback or updates but received none. A heads up that the hiring manager was unavailable and on vacation would've been nice. After three weeks of waiting, I was contacted again for another onsite interview in person. I went to the onsite interview which had a lunch part to meet with the team as well. The interview pretty much was for a while day and I met with 4 people. However, all these people had engineering degrees in different fields which was unrelated to the position which I found strange. After this long process, I received a standard rejection email. No personalized email or call even after a long process. Any type of feedback would've been good for what I went through but if they treat new candidates this way, they must treat their employees just as poorly.
