It's OK to ask for some time when you need it. But I would strongly advise against making it a habit to take time after every question.

Once at the beginning, once before the math part and a third time is cool. Doing this 5 or 6 times will disrupt the conversation and create a few really awkward moments. One of the considerations is whether you can be put infront of a client without ruining the firm's reputation and if you stop to think after every sentence this will not create the strongest impression.

Hi there,

Please please don't do this.

On your point of "It's not practical to time whether I'm under 60 or 30 seconds", not only is this ridiculous (it is practical to have a sense of time in this life you're living), but you don't have to be exactly 30 or 60 seconds. Practice your internal clock...this is a life skill not just a casing still. Please do not execute an entire casing having to be told by the interviewer to talk.

Secondly, please don't take time for every single question. You're taking a piece of advice and applying it to the extreme! Instead, take time where you need it.

Finally, and this is a general tip for you as a person: Please train your common sense! This is super important. When you get advice, think about how it applies. When deciding to do something, think about how it comes across. And, of course, learn to train yourself in things that at first might seem "impractical"

Hi there,

Asking for time to structure during the case is always fine. However, I would not wait that they ask if you are ready every single time to present your structure. Just try to structure in around 30 seconds, then present - that amount of time should be enough for questions during the case.

Best,

Francesco
