I have. Im a paralegal in a City firm, we often have to turn around tasks with >2 hr deadlines, especially on transactional work like DD reports. Corporate departments sometimes pull you into a meeting with 10 mins to prep.
On a case by case basis, reasonable adjustments are all good and well and of course should be accommodated where possible, but regular deadline extensions arent realistic in this profession, especially for juniors . Theyre assessing you as a future associate. Future associates for the most part are expected to turn around work very quickly if needed, to a very high standard. As a trainee and junior asssociate, if tasks take you longer to complete, you are delaying the senior associate’s timeline to review and revert as well. Not to mention at times you’ll have several tasks at the same time with similar deadlines.
Im sure many firms say they take this sort of thing into consideration, and likely some firms dont hold it against you. But I dont see how the average City firm would be ok with candidates needing regular deadline extensions (and accrue more fees for clients). They likely assess you at the AC on a case by case basis if you flag it, but if a candidate genuinely needs 25% more time to do the work, I cant see how they wouldnt hold it against the candidate.
