Tejas Networks Interview Experience for R&D Engineer 1 (On-Campus) 2023

Hi guys, hope you are doing well. In this article, I want to share my interview experience with Tejas Networks, it is a core networking company and now it comes under the roof of TATA. It came to our campus (Virtual mode) on August 23, 2023, for the role of R&D Engineer (Software) and hardware. The eligibility criterion was 10th: 75% 12th: 75% UG: 75% and only ECE students were allowed. There were 3 rounds after initial shortlisting, A total of 40 students were shortlisted for the online test and 20 were selected for the interviews, after that 3 students were selected for the R&D Engineer role while none were selected for hardware.

Round 1

The exam duration was 2 hours. The test comprised two sections one hour each.

The first section mainly encompassed aptitude questions and CS fundamentals (DBMS, OS, CN). Aptitude questions were easy and cs questions were a bit tricky.

The next section had 3 Coding ( Only c/c++) questions.

• It was very easy in we just needed to calculate min distance between a set of Cartesian points and the broot force would fully work.

• It was a hard-level question. it needed higher mathematical thinking order
  Given an incomplete integer series str, of n elements, where each element is the sum of the previous two elements and only two elements in the series are provided, fill in the rest.

Sample input: 10, _, _, _, _, 15
Sample output: 10, -3, 7, 4, 11, 15

• It was also a easy question.
  Construct an almost complete binary tree using a list of integers, A, of size N, and write a program to calculate and print the sum of the first numbers from each level.

The main challenge was time I would say for the coding section.

Round 2 (Technical Interview)

The interviewer was very friendly and initiated the discussion with my intro and then he further moved on to my projects. He then directly jumped to the coding part with the following questions:

1. How would you detect a unique number in a array containing duplicates. I just told him the approach and he then asked next q.

2. Code from scratch a doubly linked list and print all the pairs having a sum k in the list.

Then he asked some questions from oops,os and cn as well.

My tip would be stay calm and communicate well.

Round 3: HR Interview

It was a non eliminator round and After giving his intro and taking my intro he asked 1-2 basic hr questions like Why Tejas networks? And then he discussed about the location and answered some of my questions.

It came for 6 months + FTE and I was selected.

ALL THE BEST.
