ClickPost Interview Experience For Software Engineer (2023)

I Applied through Instahyre.

Telephonic Conversation with HR (5-10 mins)

HR asked a few questions like – CTC drawn, Expected CTC, Comfortable with remote, etc.

Then she explained the interview process – 2 Technical Rounds

• Technical Round 1 – DSA + CS Fundamentals
• Technical Round 2 – LLD

Technical Round-1 (DSA + CS Fundamentals) : (1 hr)

The interviewer was a backend developer

We started with our introductions and then moved to the project discussion.

Project discussion (10 min):

• I explained to him about the previous project of my company for around 10 minutes.
• There were a few questions about the architecture.

CS Fundamentals:

• He asked if I was comfortable with the SQL. Then asked two queries- Find 2nd highest salary of the employee. Find the 5th highest salary.
• Some discussion over LIMIT and OFFSET. I was not very well prepared with them.
• Then he asked about a situation where a customer orders similar kinds of food every day from a food delivery app, and how can we decrease the query time from DB.
• I gave the solution of storing in a Cache, and Then we discussed about cache-implementing algorithms like LRU. He asked me to implement it.

Problem Solving- https://leetcode.com/problems/lru-cache/description/

I could implement it partially but I explained my approach completely and the interviewer seemed satisfied with it, then he asked me to dry run for the sample input. I did that and showed my output.

By then, we were done with the interview. He asked if I had any questions.

Overall my experience was positive and I was hoping to be called for the next round.

Feedback: HR became unresponsive over texts and calls. I tried reaching out multiple times but didn’t hear from her. So, I concluded that I might have been rejected.

Verdict: Rejected
