This is going to be long, so please bear with me. After my graduation, I immediately joined a company. I worked there for about 5 months and I resigned from my job there to go to a better company. Please note that I left this company by serving the notice period and on good terms. I do have the relieving letter from this company.
My second company asked me to sign an employment contract (Bond) with them, I agreed to it. They gave me the legal documents to sign it, but they forgot to get it back from me. Due to the hectic schedule, I forgot to sign it and it was left in my cupboard, unattended. Eventually, I forgot about it. My new job was hell. I was asked to work for 14 hours daily and even on Sundays (which was the only work off day in a week). The work environment was hostile and superiors were borderline verbally abusive. After 2 months, I had enough of them and decided to quit the job. I told my manager and the general manager about this in person and left the job. I got no call or email from my employer regarding my absence, however, my last month salary was withheld.
Then I joined a small scale industry (my third company) and worked there for 2 months and I left them on good terms. I do have a relieving letter from them.
Now I'm in the final round of an interview with a big MNC. I did not mention anything about my stint with the second company in my resume. I have the relieving letter from both the companies that I have mentioned in my resume. But I'm afraid that they will find out about the second company anyway through EPF (Employee Provident Fund) or UAN (Universal Account Number used to map provident fund accounts to a user) account or through the background verification. How can I handle this situation?
