What you will learn in this lesson

  • Which questions were asked at 17 companies
  • Where to find each full answer
  • How to prepare for a company in one week

Why: the problem

Before an interview at TCS or Amazon, you want to know what they ask. Public interview stories on LinkedIn, Glassdoor, AmbitionBox and GeeksforGeeks help with that.

What: how this list was made

We read public interview stories from candidates. A company is named only when a story says the question was asked there. We wrote every answer ourselves, in simple English.
