See after BSc getting a job is very fussy. Although you can try but as you said you want to become Data Scientist then you have to data science. Now for that you can do a MSc in Data Science or Mathematical Statistics.

There is a exam called IIT JAM which offers admission to Mathematical Statistics MSc course in IIT;s which you can pursue. As you know IIT's have great placement cells as well as you will get the knowledge from the best of the teachers in India. Also your dream of Data Science will come under this.

The second option is Master of Statistics from Indian Statistical Institute. The MStat program is really a unique and imparts a lot of knowledge in computational statistics. You can become the part of the fatternity of the best of the mathematicians in India as well as you can fulfil your dream of being a Data Scientist.

Now if you want to go for Data Science then you can pursue MSc Data Science course offers by some of the colleges in India like Chennai Mathematical Institute, Ramkrishna Mission College etc.

Also you can go for MCA courses with specialization in Data Science. Now depending on your interest you have to choose the pathways. There are a infinite possibility of ways to be a data scientist, I mentioned some of the most certain ways to be one.

MAC didn't have any data available online for BSc Mathematics Placements but as per the official the companies visiting the college are:

• Prime Focus
• Vistara
• Oyo
• Yatra
• Vibgyor
• Genre 8
• Go Air
