Round-1 The first round comprised of 60 MCQ questions including aptitude, reasoning and English. Suggestion- The question paper was not tough but it was lengthy. If you have a good knowledge of some basic concepts of Time and Work, Speed Distance, LCM and HCF, Pipes and Cisterns, Simple Interest, and Compound Interest, it will be easy for you. There will be some basic questions in the English section which will check your grammatical knowledge and error correction. The easiest part was reasoning, I seriously suggest you all go through the questions related to puzzles. This is an elimination round. Tips- Don't spend too much time on specific questions if you are not able to do it on the first attempt. Round-2 The second round is Technical Interview which lasts for about 40-45 minutes. Suggestion- If you are from a Computer Science background, then don't expect questions related to programming languages like Java, and SQL. This is not the demand of the company. Ericsson mainly focuses on students from ECE backgrounds because it is a telecommunication company so no questions from programming languages. But they will ask questions from Computer Networks, they told me to design the OSI Model and ask questions from the OSI Model. Then they continuously ask questions from Computer Networks for 20-25 minutes which include what the is Router, the Difference between a Switch and Hub, What the is Repeater, the Full form of LTE, why the demand for 5G increasing, etc. However, in the last, they asked questions on Bubble Sort just because I am from a CS background. After that, they asked what is AI, What is the future of AI, and What are neural networks, and deep learning. This is also an elimination round. Tips - Go through computer networks thoroughly, and read all the interview questions related to Computer Networks. Round-3 The third round is the HR Round which lasts for 10-15 minutes. Suggestion- They will ask simple behavioural questions, nothing more than that. If you are selected for the technical round then it is definite that you will be selected for the HR Round too. Tips: Know yourself before any interview. Be calm, and patient and answer politely.

About Ericsson Interview Reports
This question was reported by a candidate who interviewed at Ericsson. 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 Ericsson are the higher-signal extractions to take from this report.
For broader preparation context, the Ericsson 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 Ericsson reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Ericsson 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 Ericsson 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.
