Orlando Office. The time frame from scheduling an initial interview to receiving an offer was less than 2 weeks.
My initial interview was with one of the senior managers for 45 minutes over Zoom. He gave me an overview of the company, what the job was, what it wasn't, and exactly the type of work that I could expect based upon the different teams. It was great. The manager was very friendly, and I left the meeting encouraged.
I had a 3 hour panel interview the following week which was split up into 5 sessions.
- 45 minutes with 2 product owners
- 30 minutes 1-1 with a senior dev
- 30 minutes 1-1 with a senior dev
- 45 minutes with 2 senior devs
- 15 minute wrap up with senior manager
None of the panel interviews were high stress. The first 3 sessions were people trying to get to know me, what my background was, what my skills are like, etc. It was very conversational in nature. There were still plenty of questions asked, but they were generally software development related and not the "tell me about yourself" or “do you know this obscure CS fact”. From a talking time perspective it was a pretty even split and I got to ask a ton of questions.
The last session was a C++ skills and a coding quiz. This session was a bit more structured and formal. One of the developers asked me beginner to intermediate level questions about C++ for about 15 minutes. No trick questions, just general STL and modern C++11/14 language features. Since the interview was over Zoom, I shared my web browser and the coding test was given in an online IDE. I had 30 minutes to do an easyish/intermediate LeetCode style question. I was given some starter code, which helped, and I coded a solution and a quick unit test to validate the results. I narrated my thought process the entire time I was coding, and I did get stuck at one point, but the interviewer was able to give some guidance. The question wasn't crazy and appropriate for the amount of time I had. It seems like Luminar is just trying to see if you can code using data structures and algorithms.
Overall the interview process was incredibly fair and went much better than I was anticipating. I was dreading having a drawn out FAANG style interview.
If you're looking to interview I would say know your modern C++ (and C# depending upon the job), maybe take a MOOC if your CS skills are rusty, and grind on LeetCode for a bit to get used to the problem-of-the-day style coding.
