Got a phone screen first, then had to do 3 hackerrank problems. The first two were pretty easy, but the third one was a dynamic programming knapsack problem. All 3 problems were linked and built on each other. Like, imagine designing a vending machine message system. First part: given drinks, prices, order, and balance, print change message or insufficient funds. Second part: now you can use balance or rewards points. Third part: optimize for cheapest drink price with a reward scheme. I passed the hackerrank, but I'm still in the middle of the interview process. It felt easier than Intuit but harder than the US Govt Tech Force interviews.

Got an OA first, which had 3 questions to be completed in 60 minutes. It included a dynamic programming question, a SQL question, and an API-based question. I passed all test cases for the SQL and API questions, but not for the DP one, so I didn't move on. The DP question was tough! On the bright side, it was good to see questions that seemed relevant to what a Software Engineer actually does day-to-day, rather than just pure competitive programming stuff.
