mmm I agree with Luvbolide - I am a VP at a large US investment bank and recently had an interview. I usually wear my H scarves at work in an ascot knot but for the interview I left him (my scarves all have names!!) at home. I was being interviewed by a woman and I was concerned that an H scarf might be a bit too much - maybe it is my paranoia but I have had a few snarky comments from workmates about my scarf. BTW this is in London and I would definitely say that H scarf for a tech company might not be appropriate at any time unless you are in management/finance that sort of thing
