Rippling Software Engineer II interview questions

I had a 1st round with the HR, then a Live coding asked to solve a real life scheduling problem - it went very well, I implemented what was asked of me while optimizing the solution as well... to not get a response afterwards! imho they're just gonna waste your time.

Average experience. Interviewer asked to solve a problem where, I had to code a question, it was not clear what type of coding the interviewer was expecting, specifically if its a DSA question, or LLD. Interviewer initially asked me to code as I would in my company, but later, when I started handling concurrency, intervierer told that this would be a time taking process, to not check for any concurrency. So, I gave an approach with the fastest algorithm. It was quite confusing.
