Affirm Interview Experience For Software Engineer

• This round was a one-hour scheduled coding interview with an Experienced Software Engineer working at @Affirm. The interview began with an introduction by me and the interviewer.
• This coding interview took place on “CodePair”.
• The question I was asked was similar to “Design Hit Counter” on Leetcode but there were few specific constraints and changes related to the problems the company currently deals with.
• The naive approach to the problem was to implement it with a queue and I did the same.
• The interviewer somehow did not seem satisfied with the solution but we had no time left for discussion and had to conclude.
• Another question I was asked was Insert Delete GetRandom O(1) – Duplicates Allowed.
• I was able to solve the basic question in 30 minutes. Additionally, as a follow-up he asked to implement a delete function with a twist that there can be duplicates as well and the function should run in constant time O(1).
• I tried till the last minute but was not able to achieve it in O(1) and the time was exhausted.
• Lastly, the interviewer provided me with an opportunity to ask about any questions that I might have. I asked him about a few challenges he faced in his project at Affirm.

Tip: Always use the opportunity to ask the interviewer a little about his project, challenges, company’s tech stack or missions to show that you are genuinely interested in joining the company.

• This was a 1 hour Technical + Managerial interview scheduled with a Software Engineering Hiring Manager at Affirm.
• The Manager was amiable and it was a nice experience overall.
• Firstly, the manager gave me a short introduction to his background and the technology stack he works on at Affirm. Likewise, I shared a little about my experience and projects.
• He then asked me a few questions on my recent internship which was mainly related to Python and LLM’s. He also asked me to share about any project that I have built from scratch. I shared about a full-stack web application that I built during my academia.
• My project was mainly on Angular, Node.js, Flask and AWS. He asked me multiple questions on why I chose a particular technology for a problem and why not the other one. I was also asked about the scalability of the project and how I managed to deploy it.
• Later on, he asked me a few leadership questions, questions about my strengths and weaknesses.
• Lastly, he allowed me to ask any questions and here I asked him about the technology stack his team uses and what challenges are they facing currently. He gave satisfactory answers to every question and the interview concluded.
