Trending @Infosys; While withdrawing resignation, will it require managers approval?

It depends once you place the papers and all the approvals are done then for taking back the papers also you need approvals, else no approval is required

If you are withdrawing resignation you will require manager, DM and HR’s approval because you will not be able to resign in the last week. If you are not resigning in the last you will be able to take back your resignation. It happened with me I took back my resignation before the last working day and they approved it.
