M.Tech after Msc?

Hello !
First of all ... i admit that all mistake is mine !
Just after my HSC (12th) i had a deep interest in astronomy and space science ...
i took admission into BSc ( physics ) aiming for specialization in astrophysics.
but over the time while pursuing my Bsc i realized that i am losing interest in that field. And eventually i lost it all !
m not as much curious about space research as i was 3 years back .
Besides ! there are some other reasons ( religious ) for the withdrawal of that field !

Truthfully! i've always been into cars !!!
If i would , anyhow , could time travel , i would go back ... tear out that Bsc admission form prepare for that entrance and hit for an engineering degree !

I have found this forum really really very useful ... ( basically i'm fed up googling about career options after bsc ... scope for msc ... and all that stuff !!! )

Now i've completed my Bachelor's ( 2014 ) and i am at a point of extreme confusion !!
i am about to take admission into Msc physics ...

Following are the questions for which i am seeking answers for ... !

1. Should i go for an M.Tech after MSc ???

2. If yes ... will there b any complications in placement after M.Tech ?? Since my base is of pure science until Msc and all of a sudden i jumped into technical field M.tech ... unlike the students with pure technical background ( B.Tech ) .

OR

3. Can i get a technical job in any industtry after Msc ... as i am not at all into teaching !

( please kindly do not convince me to pursue my career in space science )

please !!! i am expecting a quality thread ahead ... please help me out !
