I have accepted a company's letter of appointment since I didn't have an offer and wanted to join the company. In the letter, they didn't mention the joining date but said that it will be conveyed later. They held a five-day induction program which I attended and on the fifth day told to join the company from the next day. But now I don't feel the company has a job role of my interest and don't want to join. Can the company take legal action against me as I didn't actually start the job yet? Also, it was stated in the letter that if I didn't complete my retention period (1 year), I will have to serve a notice period of 3 months or, if failing to do so, return the money equivalent to the last 3 months' salary even though I have not joined the job yet.
