If you join bigger companies and regulated industries like banks and financially institutions, you will find that HR is mandated either by global/regional policies or regulatory requirements to screen and verify each candidates.
If you are found out you will either be:
1. Blacklisted by Group HR and from my experience, large cap companies' HRs all mingle with each other and they regularly share information so as to maintain certain standards in the industry (its inevitable that people in one banks moves to another), and this is likewise for professional firms like your Big 4. So its tough to even break it to any firms of the industry.
2. You may be reported for fraud and legal actions will be taken especially if they found out after you sign papers (these contracts that you sign on your first day covers these companies and gives them rights to do many things to you especially when you lie)
Not only will you be blacklisted and face difficulties in joining any of these firms, you will also face monetary, reputational, legal and time impact, further decreasing your chances in the future, all because of resume embellishments.
You may get away with smaller companies but for your sake I hope you rethink this in the future, especially when companies has the capability to verify your accomplishments and past working experiences.
One of my friend, a smart lad was someone who believes that he deserves better as he is capable and was not given the opportunity. So he decided to tamper his resume and gave several boosts in working experiences and even get his friends to pretend as HR contacts and references in a small company. After his assessment centre, the bank's HR came to him and wanna get him to verify some differences and gaps in his story and the fake HR story. So to retain the lies, he created more lies. At the end, HR told him which he also shared with me: "We would have offered the job to you, you tick most of the boxes and it was such a shame that you decided to lie on your resume and integrity to us is non-negotiable. You also do realise that we regularly meet fellow HRs from other banks right?"
The poor guy has the substance but a poor decision shaped his entire future and he can't get any jobs from any banks (foreign, local or otherwise). He's now freelancing and make do on odd jobs with varying pay on some freelancing platforms.
Yes, UrbanGraduate says it all.
To those who still want to embellish their resumes and make false declarations and material omissions, think again.
