There were three interview rounds, preceded by an Online Assessment. The OA had a medium-hard DSA question, one REST API question, and around 15 MCQs covering aptitude and English.

There were 2 technical interviews and 1 HR interview.

They asked about my project and some medium DSA questions. In the second round, they asked about Linked List DSA questions, followed by a SQL query. I was unable to write the query and was rejected in the 2nd round.

The interviewers were very nice. Though they told me I could write code in any language, they expected only Java.
