- Q1. Views on their recruiting process
- Ans.
I believe the recruiting process is thorough and well-organized.
The company uses a combination of resume screening, interviews, and assessments to evaluate candidates.
They have a clear timeline for the hiring process and keep candidates informed of their progress.
Feedback is provided to candidates after interviews to help them improve for future opportunities.

Interview Preparation Tips
Experience: The questions were of medium to high difficulty. What set this test apart was the fact that each question had different weightage ranging from 0.5 to 3 marks per question. Time was a major factor. So my strategy was to attempt all the 1 and 1.5 marks questions which constitute the major chunk of the paper in around 40 minutes and spend the remaining 20 minutes for the 2 and 3 mark questions. I did not even bother reading the 0.5 mark questions. The 2 and 3 mark questions were difficult and those will differentiate you from others. 1600 students wrote the test and only 86 got shortlisted for the next round.
Duration: 60 minutes
Total Questions: 40
Round: Technical Interview
Experience: I was asked to write a C program to print the Fibonacci sequence and a basic SQL query. Apart from this I was asked a puzzle and other questions related to my resume. Out of the 86, only 26 students were called for the next round which again was a technical interview.
Round: Technical Interview
Experience: This was similar to the first technical interview. I had to write a C program to print the prime numbers between 1 and 100 and a puzzle was asked again. Apart from this a guesstimate to find the number of cars between 2 places was asked and a scenario based question too was asked. These were followed by resume related questions.
Round: HR Interview
Experience: All the 26 students who attended the second technical round were allowed to attend HR round as well. This was just for 4 - 5 minutes. I was asked about my family background and why I should be hired. My fondest memories from school days were asked too. Finally offer letter was given to 10 students out of the 1600 who wrote the test :P
General Tips: Just keep a calm head and attempt the questions. Ask for time to think if you are not able to answer the questions immediately. Be bold and confident. That is sufficient :)
Skills: Puzzle Solving Capability, Ability To Think, SQL, C Programming
