Technical Coding Case Technical
It took about a month from when the recruiter first reached out until I got the offer, and that includes some time I asked for because I was on vacation. First, there was an HR screening that included some technical questions, which I wasn't really ready for and thought I'd messed up the whole thing. Then, I had a Python and SQL interview. After that, we did a product case involving statistics for A/B tests. The final round had some probability questions.

Technical Coding System Design
It was a two-stage process. The first stage was a technical screening, which was pretty easy. The second stage was more in-depth, covering Golang, databases, and architecture. Some of the questions in the second stage were code-specific to the company, but they were also easy.
Confirmed questions6 questions
- Can you tell me about Golang?
- Do you have experience with databases?
- What are your thoughts on system architecture?
