I had a really positive experience interviewing with LevelUp. After a brief phone call with their recruiter I had a video phone call with one of their dev leads. This was the basic technical interview with a couple of coding questions and then time for me to ask questions. I then visited their office for the on-site where I had 4-5 quick sessions back to back. These were a good mix of technical (including reading through code), high level design, and just personal interviews. Everyone I met with was really nice and I never once met with anyone who seemed like they didn't want to be there or anything. The recruiter I was in contact with was really great about answering all my questions and moving the process along.
