NEXTracker Interview Experience for Backend Developer (1 Year Exp.)

Hello everyone!

I’m excited to share my recent interview experience with Nextracker for the role of Backend Developer. The process comprised two technical rounds, with each assessing a different aspect of my knowledge and experience.

Technical Round 1:

The first round began with a personal introduction, followed by a question on why I was looking for a job switch. Post the introduction, the interviewer transitioned into the technical aspect:

1. I was asked to write a program for generating prime numbers, which I had to optimize during the interview while sharing my screen. We discussed the time and space complexity for each of the three approaches I demonstrated.
2. Advanced star pattern problems (2-3) were presented, which I solved accordingly.
3. Next, they enquired about my day-to-day tasks, how I approach my tasks, my understanding of the Software Development Life Cycle (SDLC), and the essential considerations while writing code.
4. We also had an interesting discussion about High-Level Design (HLD) and Low-Level Design (LLD) and whether it’s necessary for every task.
5. A question on documentation came up, specifically whether it’s crucial to document every task.
6. Lastly, I was asked to write a random number generator program using Python.

This round lasted around 1.5 hours. I was delighted to hear I cleared this round and was scheduled for the next one.

Technical Round 2:

The second round was purely technical and was scheduled for the next day. This round primarily focused on Django and some frontend aspects:

1. What is the difference between ‘make migrations’ and ‘migrate’ in Django?
2. What is Django ORM?
3. How do you authenticate which APIs a person is allowed to hit in Django?
4. In Python, even if two variables refer to the same value, are they considered different objects?
5. What is the lifecycle of React components?
6. How do you reverse migrations in Django?
7. Why do we use the @staticmethod decorator in Python, and what does it signify?
8. What are the steps and considerations when creating an API in Django?

Final Verdict: Rejected

This was a very enriching experience overall. It tested not only my coding skills but also my understanding of software development processes, design principles, and ability to handle practical problems. I’d advise anyone preparing for such interviews to have a strong grip on coding fundamentals, understand software development practices and be thorough with the frameworks you’ve worked on. All the best to everyone preparing for their interviews!

Hope this helps!
