      Senior Software Engineer Interview

      Anonymous interview candidate
      No offer
      Neutral experience

      Application

      I interviewed at Apollo.io

      Interview

      Another company that asks DSA problems that you would not come across normally, unless you dedicatedly practice leetcode. There was an initial screening round on Coderbyte - 2 medium leetcode problems Next was a Data Structure and Algorithms onsite virtual round. Question was again leetcode question - Largest Sum Contiguous Subarray (Kadane’s Algorithm) So basically, to clear the first round, practice leetcode questions, and that's it. Next was a system design round, but it doesn't look like I'll be moving forward.

      Application

      I applied online. I interviewed at Apollo.io (Hyderābād) in Nov 2025

      Interview

      Every round is a knockout round. There are four rounds for a Senior role. 1. DSA - Binary search related problem 2. Agent Assisted Live Coding round - Problem statement is closely related to Apollo.io work. You can use AI to solve the problem. 3. System Design round - Again something specific to their work. Got rejected after this round. My interview went well but they had rejected me with some feedback. I couldn't relate the feedback with my interview. There is one more round which is behavioral.

      Interview questions [1]

      Question 1

      1. DSA - Binary search related question 2. Live coding with AI - related to their work. 3. System Design - related to their work.
