Applied online and was offered an interview within a matter of a few days. At the interview I was given a paper application for employment and some other forms about myself and a privacy policy. Then I had to take a 30 minute written test, about 20 short answer questions on waves and electronics that you might see in freshman physics courses and labs. I feel like the questions were more to make sure you actually had basic physics courses rather than looking for a deep understanding of a particular phenomena or piece of equipment. I then had an interview with a manager that I thought was very relaxed and engaging as opposed to an interrogation which I feel like a lot of interviews tend to be like. After the first interview I had a second with a different manager who seemed interested in my background but we didn't have an in depth conversation because unfortunately for me I would require a higher salary than what an entry level position would reasonably pay since I would have a very long commute and can't relocate because of family reasons (on the application they ask for your required minimum starting salary).

Pretty standard interview process, 1st round phone interview, 2nd round on-site interview with manager and director, 3rd round with executives. Overall around a month due to rescheduling on their end. Feedback on each round took a couple days to get back.
