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. https://www.geeksforgeeks.org/dsa/connect-n-ropes-minimum-cost/ 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.

About Tejas Network Interview Reports
This question was reported by a candidate who interviewed at Tejas Network. LeakCode aggregates interview reports from 10+ sources, including 1Point3Acres, Glassdoor, LeetCode Discuss, Blind, Reddit, Indeed, and Nowcoder. Each report is translated where necessary, deduplicated against existing entries, and tagged by company, role, round type, and reporting date.
Use this question as one calibration data point, not a memorization target. Companies typically rotate their question pools every 2-4 months; the exact wording of a 2024 question may differ from what you encounter today. The underlying pattern, difficulty level, and follow-up depth at Tejas Network are the higher-signal extractions to take from this report.
For broader preparation context, the Tejas Network interview process typically includes a recruiter screen, one or two technical phone screens, and a 4-5 round on-site loop covering coding, system design (at L4+ levels), and behavioral. Reports tagged on LeakCode show the round-by-round distribution and typical difficulty calibration. To browse questions filtered by round type and seniority, use the company hub linked above.
How To Practice This Type of Question
Solve similar problems on LeetCode under timed conditions (25-35 minutes per medium difficulty). The goal is pattern recognition: recognize the underlying technique (sliding window, two-pointer, BFS, memoized recursion, etc.) within 60-90 seconds of reading. Strong candidates verbalize their hypothesis out loud before coding, then iterate based on feedback. Weak candidates dive into implementation immediately, lose time on the wrong approach, and run out of time for follow-ups.
Companies update their question pools every 2-4 months. The exact wording of any given question may have been retired by the time you interview. Focus your prep on the pattern, not the specific problem. The patterns that appear in Tejas Network reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Tejas Network Round
Apply the standard interview round template: clarify requirements (2-3 minutes), state your approach out loud and confirm direction with the interviewer (3-5 minutes), code with narration (15-25 minutes), test with concrete examples including edge cases (5 minutes), discuss optimization or trade-offs if time permits (5 minutes). This template is universally accepted across FAANG and adjacent companies; deviating from it produces weaker interviewer feedback signal.
The single most predictive failure mode in Tejas Network reports tagged "no hire": not asking clarifying questions. Interviewers are explicitly trained to weight this. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into code immediately. The clarifying-question check is often the first signal recorded in the interviewer's written notes.
