I remember interviewing for a startup that sounded pretty promising. The interview was going well and then I was asked for a presentation. I told them that I was more than happy to present on personal projects (of which I had plenty) but was not comfortable sharing details of work related projects while not explicitly representing that company.
They basically said "too bad" and where shocked that I cancelled the rest of the interview. I've worked at plenty of a companies in the past where being willing to share other companies' internal work would be the red flag, and turning down such a request would be seen as a good sign.
> I would actually not apply to this company.
Sadly that was the same impression I've had, and this is from someone who has been following the author's writing for awhile. Especially in the current economic environment.
