For me, it is difficult when the 'language' used is uncommon. Misunderstanding or getting to the right response could be a challenge. For example, during my F2F interviews, there are some 'jargons' used by a couple of interviewers, and the requirements for the field assessment is to write a '1-pager', presenting my findings with the concept of 'start-continue-stop'. These (1-pager, start-stop-continue concepts) may be very common 'P&G' terms or practice, which I have to do some research online and asking around to better understand how to tackle correctly. In fact, after I joined, I realised the P&G preferred method for a 1-pager is to write with an inverted pyramid concept, with the recommendation as the opening paragraph vs as the conclusion.
