Book a coaching

Hello Team!

Have about 20 cases practiced and 30 given. Feel decently confident given the amount of time that I had to study to begin with. My question:

What do you guys do the day of an interview?

i.e. Practice a case? Do some Math? Eat healthy foods? Exercise? Do nothing and just relax the brain?

Any tips or anyone want to share their "GameDay" routine?

Just do these 4 things:

  1. Sleep as much as possible
  2. Do 10-15 min of quick math exercises
  3. Eat the right food (long carbs, no sugar. probably some sugar right before the interview)
  4. Brush up the FIT stories in front of the mirror

That's it!

Don't do any cases or anything that is consuming energy.

Good luck!

  1. Stick to your routine - wake up normal time, go for a walk.
  2. Don't drink coffee any closer than 45 mins before the call.
  3. Do 10 mins maths training - Victor Cheng or PrepLounge
  4. Do 20 mins of easy brainstorming- draw out your structure for 2-3 cases, write out some easy ways to increase revenues etc
  5. Get your room prepared and your materials - print your resume out and have it on the wall, draw up your paper into the prefered format ALSO have 1 blank paper to jot important notes down that you could clarify at the end of the call. "you mentioned this earlier and i just wanted to understand this a little more"
  6. Go over FIT stories
  7. Breath, relax and enjoy the process- They cant see you smile so try to use a nice voice and portray excitement. Tone and volume are important here.
  8. Do a lot of talking - Call your bank/ mobile company and ask some questions if you cant talk to anyone before the call. Get the voice ready.

Hope this helps.
