I’ve lied on my CV. Will I get found out?

I’ve been using the summer holidays to work on my CV and I’ve been telling a few ‘white lies’ to pad it out because I’ve realised that I haven’t been as proactive with my time as I should have been.

I’ve said on my CV that I was on the Law Society Committee, when really I was only a member. Do you think a law firm will find out that I wasn’t really on the committee?
