I applied through a staffing agency. The process took two weeks.

There were a total of three rounds:

• Round 1: Data structures and algorithms.
• Round 2: Low Level System Design, including code implementation along with a discussion.
• Round 3: Hiring Manager Round.

I had a really good discussion with the team.

Round 1 featured two programming questions. You had to share the screen with the interviewer and code on HackerRank, and you needed to pass all test cases.

Round 2 was to code for an elevator system.

Round 3 covered the current project and the design of an online examinations system with the following requirements:

• Create an online test by choosing available questions or create new questions.
• Questions can be prepared in four ways, like multiple choice, single selection, text, and boolean.
• Once a test paper is created, we should not be able to change questions in the test paper. It can be void or cancelled, but should not be able to be modified.
• Be able to share test links with candidates via email or SMS.
• Candidates should be able to submit online tests, and we should be able to store tests with candidate details in the system.
• Admin users should be able to view the performance of each candidate and the top five candidates.

The expectations were LLD, including the DB schema, project structure with classes and functions, and API structure, as well as HLD, including the tech stack and a high-level architecture view.
