Crest Data Systems Software Engineer Interview Questions
& Process

So I applied online for the SDE Intern role at Crest and got an online assessment quickly. After passing that, I got invited for interviews. First up was an Online Assessment (OA) that took 90 mins, with two coding problems (like LeetCode Medium, one on arrays/prefix sums, another on graphs/BFS/DFS) and 10 MCQs about CS basics (DBMS, OS, OOP, DSA). Then I had a 60-minute Technical Interview where I got a dynamic programming question (like House Robber II) and had to implement a Trie for autocomplete. We also did a basic System Design for a URL shortener, covering the database and API. They also asked some behavioral questions like about challenging projects and team conflicts. The last step was a 45-minute Hiring Manager Interview, mostly about my past projects, how I solve problems, my debugging approach, and how I'd fit into Crest's tech stack. I got an offer about a week later. The interviewers were nice and helpful, and they really focused on problem-solving and coding skills. Knowing DSA and system design is pretty important.

Got a call from HR, he asked me some basic question related to react and javascript. Next is a practical test (Full functionality). After that, there is one link having some javascript and react MCQs. Last is a 1hr technical round starting from easy to challenging questions.

The interview process included an online assessment, followed by a technical interview where we discussed my projects, focusing on their design, scalability, and possible enhancements. This part involved two easy coding questions on arrays and matrices, some OOP questions, and core CS concepts. The interviewers were nice. Then there was an HR interview where I was asked standard questions like 'Tell me about yourself,' 'Why Crest Data Systems,' 'Where do you see yourself in 5 years,' and about my certifications and family background. The HR person was also polite. I got the offer letter really quickly, within two working days.
