I interviewed for Spring Boot and Java.

First round was an online test. It was a 40-minute MCQ test. It was a rejection round. The cutoff will be low. Questions will be hard. It was about Spring and web services. There was only 1 MCQ Java program.

Second round - It was approximately 1.5 hours of interview questions.
