There were 3 interviews. The first was a 1-hour technical interview that tests a Leetcode-style coding problem. The second was two back-to-back 1-hour long interviews. The first of the two is similar to the first. The second is an integration interview where you have to write code to fetch (usually HTTP request) and process the data and produce some result. The final interview is a 30-min long behavioural interview with an engineering manager. Interviews focus on code quality and correctness rather than performance, write test cases during the interviews as quick tests for correctness.
