Question Details
Hello everyone! I'm excited to share my complete interview experience with Tejas Networks, covering everything from the online test to the final selection. This was an on-campus recruitment drive held at LNCT Bhopal. (A brief overview is provided below.) Tejas Networks is an Indian telecom equipment company that designs and develops high-performance networking products used by telecom operators, internet service providers, and government networks. Known for its innovation and strong R&D, Tejas plays a key role in building India's digital infrastructure. This opportunity was exclusively for on-campus students and was conducted as a pool campus drive at LNCT Bhopal. To receive an interview call, students had to be shortlisted based on their academic performance and Online Test rounds. There were a total of four rounds , and each was an elimination round: Online Test (Aptitude and DSA Online Test - on campus ( Aptitude and DSA ) Technical Interview HR Interview Each round filters candidates based on performance to select the most suitable ones.
Round 1 CoCubes Online Assessment This was an online round consisting of two sections: ● Section 1: Aptitude + Verbal Ability The time for this section was 45 minutes. In this section 15 questions were asked from English (Easy to Moderate), 15 questions from Analytical Aptitude (Moderate), and finally 15 questions from Quantitative Aptitude (Moderate).
Note: ● It is possible to change between the three parts at any time. ● The Section automatically submits after 45 minutes. ● Online Proctoring is present, camera and mic permissions are required ● Section 2: Coding (C, C++, Java, etc. programming languages available) The time for this section was 45 minutes. Three coding questions were asked, with 2 fundamental questions (Very Easy), and one medium level question. Que1. Determine the point with the minimum distance from origin. (Easy) Que2. Calculate work given force and distance, and return minimum work. (Easy) Que3. Add two numbers represented as a LinkedList. (Medium)
Note: ● Questions can be solved in any order. ● The Section automatically submits after 45 minutes. ● Online Proctoring is present, camera and mic permissions are required.
Note: Round 1 is an elimination round and both sections are mandatory. Time for Section 1 and 2 is separate, but Section 1 has to be completed first before moving to Section 2. Tip: Focus more on time management in Section 1 because 30 questions are to be solved in 30 minutes. The Coding section is easy, and enough time is there.
Round 2 HirePro Online Assessment (On Campus) This was an on campus round consisting of three sections, and each section must be completed before moving to the next round: ● Section 1: Aptitude The time for this section was 15 minutes. Total 10 MCQ questions were asked from: ● Ratio and Proportions ● Time and Work ● Mixture and Alligation ● LCM and HCF, etc. ● Section 2: CS Fundamentals The time for this section was 25 minutes. A total of 15 MCQ questions were asked in this section focusing on: ● Computer Networks ● Data Structures including Tree ● C programming questions ● Pseudocodes based questions ● Section 3: Coding (C++ only) The time for this section was 60 minutes. Again three coding questions were asked ranging from moderate to hard difficulty. Question related to performing some operations on a number depending upon whether it is odd or even and reducing it to the number '4', while counting the number of odd and even numbers encountered at each step. The final answer is the ratio of odd\:even encountered (The ratio must be in simplified form if not then reduce it). (Hint: GCD) (Moderate) A string based question involving shifting each character in the string by 2 positions, in a cyclic fashion. (Easy) A rabbit is sitting at the top left corner of a matrix, and has to reach the bottom right corner. Each position in the matrix has a certain amount of carrots. The aim of the rabbit is to choose a path that maximises the amount of carrots gained. (Hint: Dynamic Programming) (Moderate)
Note: ● Questions can be solved in any order. ● Try to solve all three questions to progress further.
Note: ● Round 2 is also an elimination round. ● The sections have separate times, and it is not possible to change sections. ● Each section must be completed before moving to the next section.
Round 3 Technical Interview (On Campus) A purely technical Interview focusing on core subjects including Operating Systems, Computer Networks, Data Structures. Resume based questions were also asked. The questions include: ● Introduce yourself ● Resume Projects (Overview) Questions based on C/C++ programming: ● Structs ● Namespaces ● Typedef ● Undefined behavior in C++ ● Segmentation fault ● Templates ● Polymorphism (Depth) ● Friend function, virtual function, etc Questions based on Data Structures: ● Based on Recursion ● Based on Tree ● Based on LinkedList ● Based on Dynamic Programming Questions from Computer Networks: ● Ipconfig and ifconfig command ● About network devices ● OSI and TCP/IP Model ● TCP and UDP ● VLANs Questions from Operating Systems: ● Threads and Processes ● Context Switching ● Synchronization ● Deadlock ● Virtual Memory ● Scheduling Algorithms Programming questions, to be coded in C/C++ only: ● Rotate a matrix 90 degrees clockwise. ● Sum of squares of all Subsets of given Array. ● Multiply a number by 2 without using a multiplication operator. (Easy) The focus was on optimizing the solutions, and trying all alternate approaches of solving the problem.
Note: ● The interview length varies for each candidate, but each interview lasted about 40-45 minutes, some extending further. ● Try to be confident even if you don't know the answer to each and every question. ● Prepare the things written on your resume very well.
Round 4 HR Interview (On Campus) This was the final round, which lasted about 5-10 minutes. The HR asked general questions including: Tell me about yourself. Questions about hobbies, other than technicals mentioned in the resume. Why do you want to join Tejas Networks? Why did you choose this college? Are you willing to relocate? Are you comfortable with any of the locations? (Bangalore/Chennai/Mumbai/Gurugram) Important Notes : The company requires individuals proficient in C/C++ programming only. Focus your resume more toward C/C++. Round 2, 3, and 4 were conducted on the same day on campus. Each round is an elimination round. The overall difficulty level of each round is Easy to Moderate.

Tejas Network Interview Process Overview
The Tejas Network interview process typically includes a recruiter screen, one to two technical phone screens, and a 4-6 round on-site or virtual on-site loop. Each round serves a distinct calibration purpose: coding rounds measure correctness, code quality, and complexity reasoning; system design rounds measure architectural judgment at the appropriate level; behavioral rounds measure ownership, leadership scope, and collaboration. Reports tagged on LeakCode from 2024-2026 show Tejas Network runs a calibrated process consistent with industry norms for companies of its tier.
Difficulty calibration: Tejas Network coding rounds typically run medium difficulty with follow-up depth as the senior discriminator. System design rounds expect production-grade trade-off articulation at L4+ levels. Behavioral rounds expect quantified outcomes ("reduced p99 latency from 800ms to 120ms") rather than vague impact claims. The candidates who advance consistently demonstrate clear thinking out loud rather than perfect final answers.
How To Use Tejas Network Question Reports
Real candidate-reported interview questions are a calibration tool, not a memorization target. Tejas Network updates its question pool every 2-4 months; memorizing exact problems risks misleading you when the interviewer uses a variant. The high-leverage approach: identify the patterns that appear repeatedly in Tejas Network reports, practice those patterns on similar (not identical) problems, and use the reports to understand the interviewer's typical follow-up depth.
Filter the questions above by round type, difficulty, and recency. Focus first on reports from the past 6-12 months; older reports may reference questions that have since rotated out of Tejas Network's pool. Reports tagged with quantified difficulty and explicit round type are higher-signal than reports without those tags. The metadata filters help you build a focused study plan in 1-2 hours rather than 8-10 hours of unstructured browsing.
Common Tejas Network Interview Mistakes
Reports tagged "no hire" at Tejas Network consistently surface a few patterns: jumping into code without clarifying requirements, coding silently for extended periods, missing edge cases (empty input, single element, large input, overflow), producing working code the candidate cannot refactor when probed, and behavioral stories that use "we" instead of "I" diluting individual signal. Strong candidates explicitly avoid these patterns by following a consistent round template.
The single most predictive failure mode in recent reports: not asking clarifying questions. Interviewers are explicitly trained to weight this dimension. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into implementation immediately. Strong candidates also verbalize their approach before writing code; weak candidates code in silence and lose the communication dimension of the round's calibration.
