This question was not a difficult question for everyone but during mine engineering it was difficult because after 40 subjects in 4 year we will got get enough time to learn any new thing apart from this subject but somehow I manage for example I learnt new course VHDL and got certified apart from my engineering subject . I think it was an additional point for me in my interview. It is not necessary that you should also do the same course but I thing everyone should learn new skills during their college.example sports, music anything which you have interest
