I was not looking for a job. An in-house requiter from the company's HR team reached out to me on Linkedin. I told them I would be interested in the job if it paid a lot and was a cool place to work at. I had a great call with a in house recruiter from their HR team. We talked about my background and the company. Then I moved on to a panel interview that consisted of talking about my resume, technical questions, and then was told to create an algorithm to solve a problem. I had to write it out on a white board for the panel to go over and critique it. I was called the next morning by HR with an offer.
