Round 1 : Online Assessment
On 24th Feb 2025, I appeared for the Online Assessment round, which had approximately 30–35 questions.

The major topics covered were DSA, SQL, Computer Fundamentals, and one coding question of medium difficulty. I solved it successfully, with 7 out of 10 test cases passing.

I found the SQL questions a bit challenging, while the fundamental topic questions were relatively easy.

After completing the round, I received an email on 26th Feb stating that I had cleared the OA round and that the interview would be conducted within 20 days.

Now, I’ve started preparing for the interview.

Round 2 : Technical Interview 1 ( 50 min )
12 May 2025:

The interview lasted about 50 minutes. First, the interviewer introduced herself, and then I introduced myself (she had 3–5 years of experience).

We began by discussing my full-stack project — a social media application — for around 10–15 minutes. She asked follow-up questions such as:

While designing the schema, what important factors should be maintained?

Why did you choose MongoDB as the database?

Next, she asked DBMS-related questions on topics like normalization, anomalies, 1NF, 2NF, and partial dependency.

After that, she gave me one DSA question: the 3-Sum problem. First, I explained the brute-force approach verbally, and then I solved it using the sorting + start/end pointer method. She then asked me to write the complete, running code for it. After writing the code, she asked me to remove duplicates, so I used a Set data structure to store the results.

Then, she moved to one easy SQL question, which I solved in 5 minutes.

After about a week, the HR called me at 2 PM and informed me that my second technical interview was scheduled for the same day after 5 PM. I accepted and revised all topics in the next two hours.

Round 3 : Technical Interview 2 (85 min)
3 june 2025 :

Interview with Manager:

I started with my introduction, and then he asked me an interesting question:

“You have a client who is using your calculator. You need to improve the calculator’s features. What methods would you use?”

We discussed this for about 20 minutes. He also asked a few Computer Science fundamentals questions.

Next, we moved to DSA:

Cycle detection in a linked list – I explained the solution verbally.

Removing duplicate contact numbers – discussed the approach.

Implement queue using two stacks – I shared my screen and implemented the complete code in 25 minutes. Initially, the code wasn’t printing any value, but after 5 minutes of debugging (by adding print statements at different places), I fixed the issue.

He then asked follow-up questions and moved to sorting algorithms:

Explained Merge Sort and Quick Sort in detail.

Implemented the complete code for Merge Sort.

Finally, he asked:

How can we swap two numbers without using a third variable?

The interview ended with him asking if I had any questions for him.

I also Clear this round .

Final Verdict :
After a month, I received an email from HR stating that the position was closed due to some internal decision. I felt truly unmotivated and upset because I had worked very hard for this role, especially coming from a tier-3 college.
