      Staff Software Engineer Interview

      22 Apr 2025
      Anonymous employee
      Accepted offer
      Positive experience
      Average interview

      Application

      I applied through an employee referral. The process took 4 weeks. I interviewed at Apollo.io in Feb 2025

      Interview

      Total of 5 1-hour interviews split over multiple days, with mostly standard software engineering topics (e.g. system design, experience, leetcode). They have fewer leetcode style problems, and a higher focus on past experience and design type questions than other companies. They forgot to schedule 1 round of interviews, which they ended up scheduling a couple days later.

      Interview questions [1]

      Question 1

      Given a string with words and delimiters, return the list of words reversed but with delimiters in the same order.

      Staff Software Engineer Interview

      Anonymous employee
      Accepted offer
      Positive experience
      Average interview

      Application

      I applied online. The process took 4 weeks. I interviewed at Apollo.io in Dec 2023

      Interview

      Recruiter call, Pitch call where they give you a tour of the product, 1 medium/hard leetcode interview, 2 system design interviews (1 for general architecture and 1 more focused on scale), behavioral interview, and a "Practical Coding" interview. Recruiters were very responsive and moved me through the process faster than any other company I was interviewing with. Technical rounds start easy, and get progressively more difficult as you are able to answer things. Practical coding round was pretty open-ended, kind of like a system-design round but translated that into reasonably functional code.

      Interview questions [1]

      Question 1

      Sliding window function, typical system design questions. "How to do 'X' efficiently when you are dealing with billions of records?" STAR format behavioral questions.
