DotPe(Gurgaon) Interview Experience | (Off- Campus 2020 for Software Developer)

I had applied to DotPe off campus for Software Developer by contacting HR through Linkedin .

Firstly HR Contacted me and discussed some basic things of my background and fixed a first interview.

The first round was conducted on Google Meet.

First Round –

Interviewer asked 3 coding questions one by one and told me to write on editor (link shared by him.) and had a good discussion on each question.



Discussion like : How I go through the approach and all.

Link of the questions given below:

1. https://leetcode.com/explore/other/card/30-day-leetcoding-challenge/528/week-1/3288/

A detailed discussion on the second question.

Second round –

2. https://leetcode.com/problems/populating-next-right-pointers-in-each-node/

3. Generate unique id for incoming stream of numbers. Without using any pre lookup.

Like if a number comes again then we have to assign some different id which i already assigned to that number previously.

For Example:

1 —–> a

2——-> b

1——–>c

Without storing the mapping of previously assigned id.

Answer of this question: id+ timestamp
