The interview process wasn't too hard. They asked about what programming languages and technologies I'm good at, and then asked a bunch of behavioral questions. I talked to three different people, two from the tech side and one from HR.

Behavioral Technical Coding
I went through 2 rounds of interviews. First was a phone call that was mostly behavioral. Then, I had an onsite interview. The onsite started with some basic questions like 'What is a garbage collector?' and 'Describe how you can still have memory leaks with a garbage collector.' It progressed to more complex data structures and sorting algorithms, but wasn't too difficult if you knew the fundamentals. They sent me an offer via email and I got an extension when I asked.
Confirmed questions3 questions
- Sorting singly linked lists, and creating min/max heaps from sorted arrays, etc. At this company, I honestly think the behavioral part may have been more important.

Behavioral Technical Other
I applied online and heard back after about two months. The first part was a phone interview where they mostly asked about my background and what I'm looking for. After that, I was invited for an onsite interview. It was a panel with around 8 managers and architects who discussed their work and mine. On the same day, I also had to take an aptitude test.
