Today we are back with the resources as promised on how to approach guesstimate and case interview questions.

  • Interviewers only check your thinking ability or approach when they give you an guesstimate question.
    For example- how many flights departs from Delhi airport in a day. No body knows the exact value and 90% of the times the value estimated is far off from the real value and so what matters here is the way you build your solution step by step.
  • Second basic rule while giving an interview of this sort is to always keep interviewer in loop with your thought process.
    It should be like a conversation going on with you asking him about the assumptions being valid or not and him being giving you tips.
