can I get job in infosys after completing m.tech from ipu but I've already done BCA and MCA from IGNOU please reply
You can apply for openings for BCA and MCA qualifications. You can't apply for Mtech as you haven't done BTech. With out graduation in BTech you can't do Mtech.
In other side, Infosys hired MCA students every year so just apply for off campus and pass all the rounds and get a job.
They basically have two rounds. 1st one is written and other one is interview. Two level selection and with some time practice you can crack it.
Hope it helps you!
