Initial Screening
It was a call with the recruiter to check basic qualifications and see if the candidate was a good fit for the role. They focused on alignment with the company’s core values, such as collaboration, customer focus, and a results-driven mindset.
Round 1: DSA + JavaScript
It was a normal algorithmic round with a couple of questions:
- I got a Leetcode question: Move Zeroes
- There could be more than one DSA questions here. Other questions that I practiced were merging linked lists, counting elements in two arrays, min stack, and others.
