Nasty practices of Indian Tier 1 and Tier 2 companies.
to prevent fired senior employees from getting jobs in other Tier1 and Tier 2 companies have come to informal agreement and shared the database and are not hiring senior employees even if they have reskilled with latest tech - Bigdata, machine learning, IOT etc.
Stone walling tactics like gaps, why u resigned without job ? how did u learn new tech etc are being used.
When a senior government official enquired on behalf of his relative, the reason given was even more nasty - Since one nasscom member has labelled the person(falsely) as non performer(by manipulating data) if other company hire the company which fired him will be proven wrong, so the syndicatehas decided to use enmasse bluffing to boost profits.
