Total 2 rounds:

1. This round was with engineering manager discussion: Here all are theoritical questions on magento (as there primary tech is magento), few from resume and question like: how I will improve a API call from 1 service to another, for example Magento to a nodejs service! what steps I will take.
2. In this round, the interviewer was very chill, he first start off with discussion on caching, DB query optimization some DB level theory question and at last 1 DSA question was asked to store all 0's, 1's in order without using any addition storage and solution must be in o(logn). Pretty easy question though.

The interview went smooth and good, expecting a offer from them, just waiting for HR confirmation.
