The interview process included one HackerRank test followed by three rounds of interviews.

Round 1: Focused on problem-solving.

• Question 1: Find the majority element.
• Question 2: Given a 2D matrix with values in each cell, find the path from the bottom-left to the top-right cell with the minimum cost.

Round 2 and 3: These rounds were scheduled on the same day, with two interviewers for each.

Round 2: Involved in-depth questions on Spring Boot, along with two data structure questions.

• Question 1: Find the median of two sorted arrays.
• Question 2: Find the number of islands in a matrix.

Some questions were also based on my resume. Preparation for Java and Spring Boot is crucial, as questions covered Spring Boot architecture, AOP, and Inversion of Control. The interviewers asked numerous questions and provided limited time for problem-solving, appearing to be in a hurry.

Round 3: This was a design round where the task was to design a URL shortener service.
