One of the worst managers of IBM India is Usha rani bhumagani aka Usha bhumagani. She is not mature and harasses the reporting employees. Even one month once if u come late 10 - 15 min she asks explanation
If you talk for 10 Min’s to same team colleagues she shouts and asks to get back to work, even if work not there. She moves her staff here there other accounts showing all possible reasons. Many more stories like this. Ask people about her and they only will tell you.
She is a bad manager, don’t work into her.
