Consequences in Government Job

I'm 27 Years old living in Delhi originally belongs to bareilly. I got married in the year 2010 when I was 17 years Old. Right after wedding I shifted to Delhi with my wife, We started getting issues in the marriage and she went to her father's home after 2 months, Since then she is living in her dad's home only. We have one kid who was born in her parent's house and living with her. I filled the divorce petition in 2011 and fought the case till 2018 but got no success and I left going to court which was resulted in rejection of petition. In the middle of this I got married again in 2014 and living with my wife in New Delhi. My ex-wife still didn't get marry and living with her parents. We have no contacts since 2010. Now the question is: 1. I got selected in government job (A group), How my old marriage will affect my joining and what consequences I can face? 2. Can I file divorce petition again and what's the success ratio to get the divorce? 3. How can I save my job, will she still claim nominee for any government's benefits?
