Walmart | Flipkart | Salesforce | Tekion | Everpure | P44 | IDFC First Bank Interview Experience

Over the past 12 months, I have sat in dozens of interview, stared into countless Zoom screens, and put my heart on the line for several different companies. After a grueling year of pushing through the "no's," the tides finally turned. I successfully secured offers from a few incredible companies. Sharing my interview experiences and giving it back to community.

Interviewers grill a lot on whatever approach you take(expect questions on OS level and optimisations on OS level) and expect to solve it in easiest way possible.
