DevRev Interview Experience for Developer Trainee
Last Updated :
28 Jul, 2023
The process for On-campus placement was the same as interested students were required to fill out the form then around 600 students were shortlisted (from 3 colleges). All the shortlisted students were given different projects based on their interested fields.
All available fields were:
- Frontend Developer
- Backend Developer
- Full Stack Developer
I opted for Full Stack Developer and was supposed to complete a project – Flight Ticket Booking System in 36 hours. I completed it successfully and the company took around 10-15 days for reviewing all the submitted projects then they schedule interviews of 5-7 students each day and it goes for 3 days which means approx. 20 students were shortlisted. Students received the mail around 4-5 hours before their interview.
I received mail at 10:30 AM and my interview was at 04:00 PM. In that period of time, I can only brush up my concepts that I have learned so far which include:
- Core Subjects – OS, CN, DBMS, OOPS
- Technical Concepts – HTML, CSS, JS, Node.JS, Express.JS, and MongoDB
- Go Through my project once
- Some DSA concepts.
That’s all that I have done before the interview.
Once the interview started, everything goes with the flow:
- I was asked to introduce myself
- The interviewer asked to show the hosted project along with the source code
- The interviewer asked some questions about my project and asked to explain some specific parts of the source code.
- Then the interviewer asked about the language in which I like to code (In my case it is Java)
- The interviewer asked me 2-3 questions about java and OOPS:
(a) Is Java pure Object Oriented?
(b) Difference between Abstract class and Interfaces
(c) Difference between Final, Finally, and Finalize
- In the end, the interviewer gave me a DSA question on Leetcode only which was of Medium Level but gave me only 10 minutes to solve because of less time, so I explained my intuition and the interviewer was satisfied with the answer and didn’t bother to see the whole code.
