I am surprised that the university gave out a graduation mark sheet in the name XY.
A. Will it cause any problem while applying for government jobs and how?
It will create problems because all the applications for government jobs are becoming online. Many instructions quote 'that future queries for name correction or data correction will strictly not be entertained.'
Whatever you enter, it has to be validated by you by producing the relevant documents at the time of document verification. Similarly, a discrepancy in the name will stand out when you apply for a passport, visa or a bank account. If you have any property that has a different name then it will also pose problems at the Government offices when you pay taxes or sell it.
B. And if it causes any problem, how to resolve it?
Please make a list of documents that do not have your proper name. If for personal reasons, you want the name as Mr.XY Kumar, then you can have it but it should be uniform in all your documents. Please verify your PAN card, date of birth certificate, caste certificate if you have, DL and voter's ID.
Also, check the correct spelling and initials of your father's name because this again can pose issues when you reach the stage of verification.
1. Name correction Affidavit
Please approach a good Notary, who will enable you to get the name change or correction affidavit done in the legal way that would be binding.
2.Once this affidavit is done, please approach the local newspaper offices and apply for the name change advert service. Your new name announcement should be published in one English and one vernacular language. Then keep the original paper adverts with you.
3.Correction of 10th and 12th marks card
Please approach the principal or Head of the institution (of the 10th and 12th college), write an application requesting the service of the name change. You have to forward the application through the principal to the respective state boards of 19th and 12th.
If you have done you CBSE, the format is similar, a prescribed form has to be filled, submitted with the appropriate fees. (http://cbse.nic.in/faq/MM%202016%20Duplicate%20Form.pdf) and the guidelines to fill and submit the forms are in (http://cbse.nic.in/newsite/dup.html#guidelines).

6.Graduation Marks sheet.
Some colleges offer an online service and most by post and in person. Each university would have a prescribed form and fees to be paid. Please enclose a letter with the supporting documents for issue of a new name corrected graduation marks card.
7.Update B Tech college
Since you are in your final year, please update clearly the college authorities about your name and as it should appear on all the correspondence, degree certificate, migration and conduct certificates. This is to ensure that you do not have to run around getting these corrected at a later date.
8. Please keep all the acknowledgment slips and the correspondence numbers for the above because if there is a delay in the service be completed, these would be useful for making follow-up enquires.
