How it went
They mostly require the DSA to be gone, but what I will say is that the person who reviewed my resume was surprised by the terms I mentioned in it, such as open-source contributions, along with some graphQL and Docker things. These things impressed him more. Also, once, I failed to answer one of the questions he asked, and he started explaining the concept of langgraphs to me. I just connected that it was similar to the topic of the N8BN, and that’s where he impressed me again. We need to be much more obedient and answer clearly, and that will sort everything out.

How to prepare
Prepare DSA thoroughly, and I’ll find a loophole here. You need to solve the question using primary logic because the questions they provide are directly graph-based. However, I solve that using dynamic programming and also form that in the top-down approach, which is absolutely amazing. I only say do DSA hard, whatever the question they give, that must feel like a piece of cake for you. That process makes you a specialist.

Technical Interview60 min
It’s the HWI route. Initially, I was given the OA on July 12th, and the interview was scheduled for September 15th. I got a slot, and the interview began with two coding questions on the Infosys Wingspan portal. From there, they asked us to solve any one of the four questions. They only gave us 45 minutes to solve, and I managed to solve one. From there, he looked at my resume and asked questions in depth. You are given an integer array g of length n, where g[i] (1 ≤ i ≤ n) represents the next station you must go to from station i. There are n stations, numbered from 1 to n. It is guaranteed that every station eventually reaches station 1. Define the cost of a station i as the number of steps required to reach station 1 starting from station i (cost[1] = 0, and for i > 1, cost[i] = 1 + cost[g[i]]). Return the sum of the costs of all stations.
Example 1: Input: g = [1,1,2,3] Output: 6 Explanation: Station 1 → cost 0, Station 2 → cost 1, Station 3 → cost 2, Station 4 → cost 3. Total = 6. Example 2: Input: g = [3,1,2] Output: 3 Explanation: Station 1 → cost 0, Station 2 → cost 1, Station 3 → cost 2. Total = 3. Example 3: Input: g = [2,1,1] Output: 2 Explanation: Station 1 → cost 0, Station 2 → cost 1, Station 3 → cost 1. Total = 2.
