Coding problem3

First 10 minutes started with the Introduction. Then he asked about my projects. He seemed interested in my projects and asked a lot of questions about them. He asked questions related to Node Js, React Js, Mongo DB, AWS as all these were mentioned in my Resume. Around 25 minutes was completed explaining each and everything.

Then he started with the coding questions. I was allowed to share my screen and use any of my favourite text editors. I chose ‘VS Code’.

I was able to solve 2 coding questions very easily. I got stuck in the puzzle as I didn’t solve any puzzles before. I was able to come up with different approaches, but they weren’t the most optimal. He tried giving me a lot of hints but still wasn’t able to solve it. I had a positive can-do attitude throughout, and I was really close to solving it.

Feedback: He told me I performed well and asked if I had any questions for him. I asked for the solution to the puzzle. He explained to me the solution and I told him that I will practice puzzles.

Around 5-6 students got selected for 2nd Interview.

Coding problem1

It started with a brief Introduction and in-depth discussions on projects. He also asked me a lot of questions about my previous internship. He asked me some behavioural questions as well.

I was able to solve the question, and he did not ask me any other questions. This round was really short for me and was finished in around 35 minutes, well before time. I asked about my feedback, and he told me that the ‘HR’ will get back to me. I thought he was not satisfied with my answers and I will be rejected though I gave very good answers to every question.

3 students got selected for the next round. I think he was satisfied and did not want to waste more time asking questions.
