E2 Optics interview questions

In the beginning it was ok they reached out i had two interviews one with the hiring manager then a month later i was contacted and asked to have a 3rd interview i did and when it was done i sent a thank you email i then was then contacted to have a 4th interview i asked was this normal to have so many steps ? his response was they wanted to make sure everyone was the right fit for the office , I didn't get a offer only to be told the other person had 20 years exp . what a waste of time .

Had me come into the office for essentially screening interview. In-depth questions weren't really asked. They were interviewing a lot of candidates even though this role required specialized skills. E2's follow up was they hadn't found anyone yet who matched their criteria. False in my case, but they clearly have no problem wasting candidate's time.
