ShareChat Software Development Engineer SDE interview questions

I had 2 rounds of interviews - First round majorly around iOS and Swift concepts. Some multithreading questions - The second round concerned iOS and Swift concepts + App UI/UX understanding

Got a call from sharechat regarding an SDE1 opening, had just one interview which was PSDS. It includes answering 2 leetcode medium level problems in a span of 1 hr. The interviewer wanted the solution to be the most optimised and kept pushing on improving the complexities of alternate approaches which had similar asymptomatic time complexity but slightly more computation. Overall the problems and experience was good.
