Please tell us about your Interview procedure at Airtel (Short listing procedure, GDs, Interviews).

Apeksha Tandon Airtel Technical Interview Process NetworksThe selection procedure began with a written test which had 25 questions– 15 aptitude questions and 10 technical questions, which had to be completed within 20 minutes. It was a pen and paper round. The technical questions mainly focused on basic RLC calculations and fiber optics.

Next was the GD round. The topics for GD can be about latest technological developments in the telecom field too. Out of 53 people, 18 of us got shortlisted for PI. The interviewer generally focuses on your projects and internships. So, it is best to go through your reports before the interview round.

The questions ranged from working of a MOSFET, difference between enhancement type and depletion type to RLC filters to TCP vs UDP. Hence, a quick brush up of networking and analog/digital circuits should be done as you’re likely to be grilled in these subjects.


What makes this company different from other firms?

Airtel is a market leader in the telecom sector. So undoubtedly, anyone who wishes to pursue his career in the telecommunications field is likely to be partial towards Airtel. It offers a flat hierarchy instead of a pyramidal one which puts even the recently recruited people at ease to interact and be mentored by anyone. Apart from that, it has a fast paced work environment too.


How did you prepare for the placement season? What advice would you give to your juniors regarding the placement season?

I started with my preparations a month before the placement season. Revision of digital and analog circuits and systems is a must. I studied Computer Networking too because I was interested in a networking profile. For aptitude test, I studied from ArunSharma. I’ll like to advice everyone that please solve CAT modules even if you aren’t preparing for it because throughout the placement season, almost all companies are likely to give a CAT-like aptitude test.


What’s the role of academics in getting a good placement at NSIT?

Of course, the first thing that catches the interviewer’s sight is your aggregate percentage. And in any interview, the first impression matters a lot because if you are a topper, your mistakes may not be penalized and you’ll be given more chances to prove your mettle but if you are sitting just at the edge of the company’s cut-off, your slightest mistake may be heavily frowned upon. So all in all, if you’re interested in a technical company, a good percentage should be targeted.


Elaborate on the type of work in this kind of role?

Airtel offers the role of Young Technical Leader which is an amalgamation of both technical aptitude and management/leadership skills.


Would you like to give any general advice to your juniors?

My general advice is to start your preparation well in advance before the placement season begins because companies visit one after the other and it will be very difficult to revise again, let alone study a new concept. Further, apart from a good academic background, try to be an active member of a few societies since it displays your leadership skills and capability to work in a team.

Remember you’ve 4 years to develop yourself but the interviewer has just 25-30 minutes to judge you. So be honest.
