So far this is the only one where I've made it to the onsite. It feels like they're hiring a lot of people, and the interview came really fast after the referral.

The first round was technical, with a case and SQL. The SQL part is the trendy format these days: they give you a piece of AI-generated code and you have to pick out the errors.

The second round was the onsite, split into four parts: three case parts plus a business stakeholder interview. I actually felt I answered okay, but I think I failed on the cases. One of the experiment design parts went into a lot of detail, like whether to do a switchback or geo randomization, plenty of experiment design details. All the questions felt like they came from a question bank, and the interviewers just read them out one at a time.

Overall the cases are still the same old DSA-style templates, and the difficulty is on the low side. Maybe there really are a lot of candidates.

Also, it does look like nobody there has good work-life balance, and the interviewers all seemed miserable 😂
