Real question. What would you answer when asked:

imagine that it is Fri 4pm, presentation for the client demands 15 hours of work to be 80/20 or total of 25 hours of work to be 100% ready. You are about to start the bachelors party of your best friend in 4 hrs and you are the organizer for entire group that does not know the details, what and where will happen. Your partner needs it Monday 9 am for review.
Partner not available for consultation.

Hello!

Honestly, they would never ask you something like this.

Precisely for the fact that does not reflect reality:

  1. You would know, if you are the poor bastard who needs to do this, how important it is for the client and the engagement. You will have the info you need to see whether is good or not to do 8020
  2. Partner will be available at some point to double check. In the real world, people don´t disappear.

Hence, don´t loose time with these things and focus on the real case + FIT prep.

Hope it helps!

Cheers,

Clara

Well, first you need to clarify the objective :)

If this question is during an interview, we both know what you should say your objective is: "To be clear, my objective here, first and foremost, is to fulfill the duties of my job as I know what I'm signing up for. My secondary objective is to ensure my friend has a good bachelor's party"

Then, you need a framework.

Bucket A is how to fulfill your work duties efficiently

Bucket B is how to meet the needs of your friend.

If you're "smart" you tell the interviewer "I have to work 25 hours to get 100%, and 15 for 80%. I would check with the Partner whether we're looking for 80% or 100% for his/her review. I also need to be sure I have enough sleep to perform during the week"

You can realize that, between Fri and Mon you must have 24 hours of sleep, leaving you with 41 waking hours (65 total hours from 4pm Fri to 9am Mon minus the 24 hours sleeping).

So, actually, this problem isn't that hard...you can do both :) But, you would likely need to breakdown how you setup the party for success (contact your friend's other friends), plan your Sat+Sun working days on the Friday, then attend the party but stay sober etc.

Dear A,

I would recommend you to read "& principles of highly effective people" by Stephen Covi, where you can find proper explanaition of hor to prioritize urgent and inmortant tasks, non-urgent and inmprtant task etc.

Basicaly it depends on your values and your responsibilities.

Also, many expert may agree with me, that work-life balance in consulting is not there.

If you can't connect with a partner, then connect with one of the closest friend and explain him details.

Best,
André
