Technical Coding Behavioral
So I interviewed and it was a good experience overall, even though I didn't get an offer in the end. It started with a quick chat with HR over the phone, then I had to do a take-home test that involved working with JSON files. After that, there was a technical interview where I had to do some live coding in Python in a shared document. The coding problems weren't too hard, but coding live is always a bit nerve-wracking. They also threw in some order of magnitude estimation questions.

Coding Technical
I had an initial chat with the recruiter to review my resume. Then, I was sent an online assessment with multiple-choice questions and two coding challenges. After that, I spoke with a software engineer for an interview that covered both coding and brainstorming. The coding part involved merging two datasets according to specific requirements, and the brainstorming part was about how to validate place data.
