That sound like a colleague I used to work with, for many years. He has a bagful of Certificates aka Upgrading, he was a believer in that, way before the shitty Skills Future today...what did those bagful of ? do for him....he gets plenty of rejection after he was retrenched from a managerial position in a Financial Institution....last heard, working as a door to door salesman...
He was not the only one I know on the 'wagon trail' of upgrading in qualifications , accreditation etc....whatever...I know many, whose doors get slammed in their faces..for (1) They are Singaporeans (2) Too qualified (3) We "prefer females", (4) "you are too old"...
Like your brother...many of these I know have few vices...... what's the use of all these upgrading etc..when, doors get slammed in your faces?? the excuses is "for we can get plenty of Foreigners out there" just one of the excuses ....can one not get Xenophobic over this...when your belly is hungry!
