Round 1 Online test
● This round was conducted in online mode on the AON test platform. The
duration for this round was 1hr 15 mins
● This round had 2 sections: i) Aptitude ii) Coding
● Aptitude section had questions from general, logical, mathematical aptitude.
Practising questions from indiabix.com, faceprep.in etc would be of great
help to do well in this section.
● Coding section had 2 coding questions. The questions were:
a. Check whether a number is a perfect number or not. This question was
easy but the constraint was: 1<=num<=10^9.
b. Shortest string possible after removal of all pairs of similar adjacent
characters. This was a medium to hard level question.
● Solving questions on platforms like GeeksForGeeks, Leetcode etc., would
be of great help to do well in this section.
● Overall, this round was easy to medium.
Round 2 Psychometric Assessment
● This was a non-elimination round. It was an online round.
● Questions will test your personality and work behaviour so there are no right
or wrong answers in this round
Round 3 - Group discussion
This was again a non-elimination round. However, performance in the group
discussion was considered for final evaluation.
● We were given 3 topics and were asked to choose one topic. The topics
were:
○ Pros and cons of monetizing digital creations like YouTube, Instagram
etc.
○ How can we make internet a safe place
○ Cashless economy - a boon or ban
Round 4
This was an offline round and it went on for 45 minutes. There were 2
interviewers in this round.
● Some of the questions asked by the technical interviewer were:
○ What is an API?
○ How does a request from a browser go to the server?
○ What is a session and how a session is created between the host and
the receiver?
○ How do you think push notifications work?(He just asked my logic on
how it may work)
○ Coding: Given a number n and n-1 numbers(which will be from 1 to n
only) find the 1 number that is missing in this sequence. For example:
n = 6, the numbers are: [1, 4, 6, 5, 2] O/P must be 3
○ Logical puzzle: There are 10 machines which produce coins of equal
weight, size, colour etc., One of the machines is faulty and produces
coins of lesser weight. You now have a set of coins and an electronic
balance(not the traditional 2 sided balance used in grocery shops).
Using these, you have to find out which coin is faulty.
○ Real time usage of polymorphism
HR interview
○ Introduce yourself
○ Give instances where your ideas were not accepted by your teammates
and how did you feel?
○ Tell about an achievement in your life
etc.
