I applied through a recruiter. I interviewed at HashiCorp
Interview
I applied for (Site Reliability Engineer II - HashiCorp Platform DR) and the Code Pair round experience Format: Live Coding (60 Minutes).
The Task: Unlike standard LeetCode problems, this round was practical and object-oriented.
I was provided with a Skeleton Class and specific Function Signatures.
Interview questions [1]
Question 1
Round: Machine Coding / Code Pair Question: "Simple Database" (In-Memory Key/Value Store) Details: I was given a skeleton Python class and asked to implement a database library that supports basic SET/GET/UNSET operations.
The twist: I had to implement Nested Transactions.
BEGIN starts a transaction (can be called multiple times to nest).
ROLLBACK reverts only the latest transaction.
COMMIT finalizes everything.
I applied online. The process took 3 weeks. I interviewed at HashiCorp (Bengaluru) in Feb 2025
Interview
Applied through Job board, lengthy process.
Python is taking over world.
Interview was fine, Interviewer was very skilled and explaining everything again and again. i passed 2 rounds initially Coding assessment from Code Signal and Screen round and now Hiring Manager round where he asked Java basics (Since i knew java) and DevOps and cloud infra questions. Java question was to identify substring from give string but he wanted as per keeping in mind about time complexity meaning he said me to write multiple approach and select one with lower execution time. He was looking for python but I was from java background. Overall preety good experience as I am from tier 3 college and tier 3 company employee.
