First-hand accounts from people who interviewed at Unknown Planner.
Software Developer
The interview was pretty straightforward and they were good at getting back to me. It was like three steps: first, there was a test to see how good I am at solving problems, then a technical interview to check what I know about the job, and finally an HR interview to see if I'm a good fit personality-wise.

- What are the basics of JavaScript?
- What are your Node.js concepts?
Senior Software Engineer
The recruiter reached out on LinkedIn with the job description. I expressed interest and booked a call. During the call, the recruiter, who is the only non-tech person on the 7-person team, asked about my background. I mentioned my familiarity with their MERN stack and OSS projects. He suggested I create a PR for improvements, which I later did. He then asked for my salary expectations, and after some back and forth, I stated around 100k. He mentioned the team is moving fast and the process should take 1-2 weeks. Despite contributing to their OSS repo, which was merged without changes, the recruiter ghosted me after I followed up multiple times.

The interview process usually starts with an Online Coding Round where you'll get two coding questions to solve in 60 minutes, typically on basic data structures and algorithms. Then, there are more Online Coding Rounds (Rounds 2 and 3) to check your problem-solving skills with coding questions covering arrays, lists, graphs, trees, dynamic programming, recursion, linked lists, queues, maps, etc. It's a good idea to talk through your approach while coding. After that, there's a Hiring Manager Round where an engineering manager will ask you behavioral, resume-based, and scenario-based questions to gauge your soft skills and technical abilities. Lastly, an HR round focuses on how well you might fit into the Flipkart culture.
