This question already has an answer here:
Received a job offer for a graduate position and it was stated on the offer letter that the offer will be conditional upon a satisfactory "security screening". It also mentioned that any false statements will lead to dismissal.
I just checked and realised that some of my employment dates were inaccurate - shortened/ lengthened (I was providing a guesstimate when applying).
I also dressed up/ exaggerated on my positions and achievements of responsibilities in extra curricular activities, as well as achievements at work. Some were quite big exaggerations (i.e. false statements).
Should I be worried that I could lose the offer/ fail the screening? I am very paranoid and regret this, not sure what to do.
