hi,

see you can apply as a computer science faculty in engineering colleges along with bsc computer science colleges to work as a lecturer or assistant professor. there is many job opportunities available after passing  mca course. it will be easier to apply for private colleges as there is many private engineering and bca colleges in india, right now computer science is a most demanding stream. when you are working as a professor you can do phd courses in parallel. many state university offers part time phd courses. you can directly apply for phd after completing mca course also.
