Difficulty: Medium to Hard

Rounds: 2 rounds (Technical Interview, Quiz Round - though the quiz round details are missing)

Topics Asked: JavaScript, Node.js, API calls, AJAX, JSON, Projects, Computer Core Subjects (Mutex, Semaphore, Normalization, OS, DBMS), DSA (Asteroid Collisions - LeetCode)

Experience:

The candidate had an interview on October 20, 2023, with around 60 students shortlisted for the interview round. A pre-placement talk was held before the interviews. The process involved two rounds: a technical interview and a quiz round.

Interview Round (Technical):
The interviewer focused heavily on the candidate's resume and projects. Initially, questions were based on JavaScript and Node.js, including:

• How to call an API and how many methods exist for calling an API.
• Questions about AJAX.
• What JSON is and its advantages over other formats.

The discussion then moved to the candidate's projects. The interviewer frequently switched between core computer science subjects, asking about:

• Mutex and Semaphore.
• Normalization (while the candidate was answering a previous question).

Finally, a DSA question was given: "Asteroid Collisions" (LeetCode problem), and the candidate was asked to write the code on a sheet and explain the logic, pointing to specific code parts. After the coding question, the interviewer returned to OS and DBMS topics. No questions were asked about OOP or Java in this round. The interview lasted around 40-50 minutes.

Second Round (Quiz Round):
The candidate was shortlisted for the second round along with 20 other students. However, due to time constraints, no further interviews were conducted on that day.

Overall Experience: The interview was fast-paced, covering a wide range of topics from web technologies to core CS and DSA. The interviewer's frequent switching of topics added to the difficulty.
