Groww is an online investment platform that allows investors to invest in mutual funds and stocks. In April 2021 the startup reached unicorn status by raising $83 million at over a $1 billion valuation.
- Selection status: Selected ✔️
- Level: Easy to Medium
- Interview and recruitment process: Good
Application Process
I Applied at Groww through the on-campus opportunity at our college. I interviewed for Groww for the SDET (software development engineer in test) role.
Structure of the interview/Rounds
1. Online Assessment
2. Technical Round
Online Assessment
Time: 90 min
Platform: Hackerearth
This round consisted of 27 questions. From which 25 were mcq and 2 were coding questions.
a) Mcq questions
The mcq’s were based on the following topics:
- DBMS
- OS
- Data structures and algorithms
- Testing
- Pseudo code
Different mcq had different marks which varied from 1–4 based on their level of difficulty.
b) Coding Questions
The coding section consisted of 2 questions from which 1 was of easy level and 1 was of medium level.
Problem 1 (20 Points)
It was an easy level problem which consisted of 20 points. This problem was based on identifying the pattern in the answers to the mathematical equation and then outputting the result according to the input.
Problem 2 (50 points)
It was a medium level problem which consisted of 50 points. It was a pure implementation problem that revolved around circularly iterating a 1D array and multiplication of matrices.
Technical Round
Time: 60 min
This round was based on testing overall problem solving skills, development skills, logical thinking ability, and personality.
Topics and questions that were discussed in this round are:
a) Coding questions
In this part, I was asked 2 DSA based questions and both were of medium difficulty level. Edge cases and time complexity were discussed for every approach I told.
Problem 1 :
It was a linked list medium level problem. The task was to remove the even numbered elements from the linked list. The main task was to cover all the edge cases in the implementation.
Problem 2 :
It was a dynamic programming medium level question. The task was to find the number of ways to make the change of N rupees by the infinite supply of a particular number of coins.
Firstly, I told them about the recursive approach, explained it, and discussed the time and space complexity. After that, I went on with the dynamic programming approach. They also discussed why dynamic programming needs to be used here and why brute force cannot be used and other related questions based on the algorithm were there.
NOTE: The technical rounds can be easily aced by practicing DSA problems on leetcode and giving contests regularly. The topics from which questions can come from are: Trees, Recursion, Linked list, String, Arrays etc. The level of questions is generally medium.
Time and space complexity determination is highly important along with identifying edge cases, fitting the right data structure, applying the right algorithm, thinking aloud, and explaining nicely.
b) Project Discussion
One project from my resume was discussed. I was asked to show the demo of the project and the questions related to it were asked. What technologies and why I used a particular technology in my project, was also discussed.
A high level design question was also asked which revolved around the online money transaction and its security in online purchasing sites.
NOTE: Be thorough with the projects you mentioned in your resume. Be sure to deploy your application this creates a good impact, prepare how you will walkthrough your application and explain it.
c) A Puzzle was asked

d) Resume Discussion
Discussion on hobbies, achievements, and skills was there.
NOTE : Don’t lie about your skills or achievements in the resume.
e) Situation based questions on leadership, team work, and problems faced during the learning process were there.
NOTE: Make sure to take these questions seriously and do not avoid them in the interview. Because the way you answer these questions create a huge impact on the interview.

Groww selected around 9 students including me from our college for SDET intern role. It was a great experience interviewing for Groww.
Recruiting process was smooth and interviewer was friendly and helping throughout the interview.
All the best. Happy Coding!!
