1 oa, hr call, then a hackerrank. 4 rounds of interviews, 2hr each with 2 different people (2 technical then 2 repetitive case studies). Thankfully i was rejected without reason after talking to the COO because I later learned its a sweatshop and your office space is 8 sq ft. Recruiter sounded like they just woke up whenever calling too. Apply if you like working with the clueless or liars because they said I could reach out to them post-interview but its radio silent on their side.
