Trending @Infosys; When will manager or HR reach out after resigning ?

it depends, for me after 10 days

Don’t worry they will, btw do you want to get retain ?? If not then just focus on giving as many as interview and try to increase you salary .. maybe a good company with high package is waiting for you ..

Usually, HR or your manager will reach out within a week or two after you resign. If they're on leave, it might take a bit longer.
