How to rejoin TCS? I have 4 years of experience in TCS, I had resigned TCS to join a gov job, but here there is no growth and posting is afh

Please help me to understand if one can rejoin TCS if they had resigned on good terms on performance and rapport with the manager. I have joined a gov job but i have realised that there is no growth and postings are far away from home in some rural place in up northern most area.
