I actually like it and recommend that under each company on the CV you include a line about what the firm does and how large it is. This saves the recruiter having to Google a load of things to make sure you’ve got the clout and industry experience to be considered for their role.
But use some fucking common sense here. Don’t insult the employer’s intelligence by stating the fucking obvious if the firms happen to be global mega corporations on every high street in the UK:
‘Tesco is a large supermarket chain that supplies food and drink and many products and services to the nation
McDonalds is an international fast food restaurant and takeaway outlet.’
