I applied through a recruiter. The process took 3 weeks. I interviewed at Thorlabs (Newton, NJ) in Dec 2020
Interview
Very long process, takes 2 to 3 weeks. You will be interviewed by 4 to 6 senior level engineers. Questions spans from basic optics to customer interaction. Questions, how do you expand a beam given 2 lenses.

Other Applications Engineer interview reviews for Thorlabs
First round was phone interview with some technical questions, not too difficult. The second round involved very specific optics-related questions with 4 different people on the team. Overall was a little tricky and unexpected because optics isn't my specialty and I had made that clear earlier. Ultimately wasn't selected for the role, but the team seemed nice - just felt that they were looking for specialized skills that weren't mentioned in the job description.

Got a call from HR and scheduled a phone interview with the manager. A few weeks later got an on site invitation. I was told a decision will be made in a week.
