His supplied quote asking if it's OK to go away and think about it comes across as weak/unsure of yourself in my opinion.
A confident candidate will TELL the interviewer that they will need time to think about it. This isn't a thing to be rushed anyway so any interviewer should be fine with this. If not, do you really want to work for someone so pushy?
Interviews are a 2 way street, a lot of interviewers forget that they are also on show to impress the candidate. Especially right now where there seems to be a lack of skilled engineers out there.
