Firstly, congrats on securing all these interview. Isn't that worth a pat on your back in these times!
And am sorry to hear you are feeling these emotions. A lot of people, if not everyone feel the nerves. You are not alone. The key thing is to learn to keep them at distance and not let your mind go out of control. You are creating too much pressure and worrying too much about the outcome. Stop doing this.
Try these tricks:
- Take one or two days off completely and do something you really like- jog, walk, games, something that will engage and energise you
- Work from a different place/room/office if you can, change of scenery helps trick the mind
- Try deep breathing, slow down your breathing when you are getting anxious
- Tell yourself to take things one at a time, one interview at a time
- Feel GRATEFUL for everything you have- your health, your education etc etc. So many people are worse off..think about it
Ultimately, the source of the problem is this: aspiring consultants and bankers are insecure ambitious, high performing people. I am generalising here but its largely true. I am one of them. Its important to give your best, manage your thoughts and emotions and let things in happen.
On the flip side if you are feeling like this in the case exercise , do you really think consulting is the right path for you? Consulting companies use the performance on case interview as a resonable indicator of real on the job performance. Please choose a career where you can be joyful, give your best and not resent every day thinking there is something better out there.
All the best and take it a bit easy on yourself.
