It comprised of 5 rounds - HR Screening - System Design - Pair Programming - Technical Discussion with EM - Discussion with Co-founder Round 2 and 3 were technical in nature, i.e I was expected to code and explain the design decisions I was taking. Round 4 was general discussion about my previous roles and Tech in general. The interview with co-founder was more like a culture fit interview, discussing about direction of the company and plans for the future etc.
