I completed 4 rounds of interviews: 1st: Call with the recruiter, the usual stuff. 2nd: Take-home test that included algorithmic exercises, a completion of a React.js frontend component and a implementing microservices for the backend. 3rd: Technical interview, mostly about Java, data streams and generics, also some basic questions about backend architecture and design patterns. 4th: Cultural interview, to make sure you're a good fit for the company.
