I applied online. The process took 4 weeks. I interviewed at LinkedIn in Nov 2017
Interview
The entire process was split into 3 rounds.
1) HR Interview
2) Coding Round
3) Coding Round
HR Round: This round is a phone interview with HR. He/She will ask questions about you, your resume, your interests and judge if you are a fit for the company.
Coding Rounds: This round is a phone interview with a Software Engineer. First 5 mins they will ask about you, your resume and your interests. Then they will share a live coding platform link. eg collabedit.com and display the question there. Once one question is done. They will display the second question. For each question, they expect you to answer confidently why you have chosen this approach, the complexity of the code, does it handle all cases? and whether your code is optimal if not how can you improve it. Do explain your code while typing. It helps them to understand your approach and if you are going wrong, they can help you. Overall they want to know whether your foundation is strong or not. Lastly min or so, they will give you an opportunity to ask them questions. Utilize this opportunity to stand out, show you`ve done your research about the company and interviewer.
The interview process started with a screening round featuring one LeetCode medium problem and an SQL challenge. This was followed by a comprehensive onsite with five rounds: a LeetCode coding challenge, an SQL assessment, a system design interview, a hiring manager conversation to evaluate cultural fit, and finally a team matching phase to find the right team.
Interviewed for an SDE role. The process was well-organized and the recruiters were responsive throughout. That said, the technical rounds were significantly more challenging than expected — definitely come prepared to go deep. Overall a valuable experience regardless of the outcome.
That was a real stroke of luck — when I got to the coding round and encountered a question on finding the maximum subarray sum, I had literally seen this exact problem on prachub.com a few days earlier. The interview kicked off with a recruiter screen, followed by a technical phone interview. It was intense, especially with the focus on algorithms and data structures. I also faced some behavioral questions that challenged my experience. After a final onsite round, I received an offer and happily accepted. Overall, it was tough but rewarding.
