What is the one word in your CV that tells recruiters you have been in the business for a long time?

How can a recruiter automatically know which “generation” of testers your are from?
What is that one word in your CV that says 80s , 90s 2000?
Mine is QTP , I think

You’ll likely find that’s an illegal questioning tactic in many countries. Some places may not even be able to ask for 10 years experience any more as that becomes ageist.

With QTP you may need to be more specific, Mercury or HP?

Also testing a system with a Btrieve file system, not worked on one of those in a while.

Which raises an interesting question, A few people upthread have already alluded to avoiding age discrimination in job applications, especially as this is, at least in theory, illegal in some countries, including the UK. As ever, the problem is proving it. I for one encountered age discrimination in a job search when I was told that I didn’t get one job because I was “not a good cultural fit” for perhaps the most monocultural office I’d seen in twenty years, but one where I would have clearly been the oldest person in the room (everyone else had hair, for a start off).
But how can you avoid exposing your age when societal, technical or professional changes have made your knowledge and experience immediately reveal your age cohort? In the case of qualifications, I could say that my degree was issued by Northumbria University instead of Newcastle upon Tyne Polytechnic; but then I could be accused of falsifying my CV to conceal a material fact of age. And a simple employment history will show evidence of age, especially if you’ve had a lot of or long-lasting employment roles.
I suppose the answer is that discriminators are gonna discriminate, and anyone with my sort of history is going to be promoting their CV on the merits of experience. And who would want to work for an employer who does not value experience?
(Actioning a discrimination case in the UK on these grounds is likely to take up time that someone engaged in a job search doesn’t really have, let alone the available head space, as opposed to actually finding a job.)
