What are the options of part time job while pursuing b.tech?

Yes,it is possible to do part time jobs while pursuing B.TECH.If you think lot of part time opportunities are there.But you have to concentrate on studies because you don't get any time while working.The part time jobs are

1.work in any retailer shops at evening times.

2.If you are in city go for call centre jobs in weekends.

3.work in any online job like theexamresults websites.

My SUGGESTION is don't go for part time jobs you will get tied and you won't get time to study.

You can do call center jobs for 3-4 hours and data entry jobs like
captcha typing
SEO jobs
Working in any mobile shop or in any internet shop
Data entry
Form filling jobs etc
In news papers you can find part time jobs.
Better to go for jobs at out side not in online.
Due to this you can improve your skills.
there are lots of chances for part time few of them given below :

COMPUTER BASED JOBS:

- DATA ENTRY

CALCULATIONS IN COMPANIES

In all the examples are few things there are lots of 
opportunity are there.

so , you can work for all the fields at the same time you must 
concentrate on you studies also its very important one . then only your
goal will be achive .

my personal suggestion is ...........try to do private tutions....it will be boost for your own studies also!!!!!!
