you may risk insecure hiring managers throwing your resume in the rubbish bin. Anyhow do you want to work with insecure managers?

Why need to delete from LinkedIn? its a crime for not wanting to flaunt academic qualifications when applying for a job? Its a smart thing to not let people think you are over qualified. Hiring managers seeing the masters degree and start thinking how long will this dude stay here until he gets a teaching role for example.

I did not put my highest qualification during job application. I did update my employee data in the company portal. no one come and fire my ass also? I dont think my boss even know or care what my highest academic qualification is.
