job purpose

In normal case there should be not much problem.  In law an accused is presumed to be innocent till proved guilty.  Mere pendency of criminal case against you should not be a problem for joining. 

Whether it is for theconcerned authority to take the final call, generally speaking, a pending criminal case should not come in the way of getting a job. You should however, declare about the pending criminal case transparently in the relevant columns of the attestation form/ police verification form when you are offered a job. 

But, after conviction in the criminal case, if any, the competent authority may take action against the government servant concerned, which may generally be removal or dismissal from service in such a case.
