Examples for guesstimate/Fermi questions

Question

Hi all,

Are there any examples(including solutions) on preplounge for guesstimate questions? Or does anyone have a good source for them on the web? Really haven't had any luck researching this so far...

Thanks!

Best,

Andreas

Answer 1

Andreas,

Case In Point is my favorite resource to practice guesstimate questions. I have used it before joning to BCG 10 years ago. I had 3 guesstimate questions during my interviewing cases.

I also used to do guesstimated as interviewer during my time at BCG. Feel free to schedule a session with me to practice & strategize

Best,

Guillem
