Legally since he seems to have incurred no expenditure on your training, he cannot recover any damages through the bond under sections 73 and 74 of Contract Act. Validity of bond is also doubtful because that would also be subject to signing your offer of appointment. Under Shops and Establishment Act, unless you have rendered specified period of service, no notice period is required to be given to resign.
