Tech Mahindra interview questions

It was as campus recruitment event at my university Sharda University which began with pre-placement talk, most of the slide covering their company detail. then there was an online test by techM for which you have to be fast try to do maximum questions in every section 180 que in 90 min. the quantitative question are though bit time taking you can manage it in English. After submitting the test the result is declared instantly after which you have to write a short easy on any random given topic. Try to write good and catchy lines and don’t focus on writing much. 1-elimination is at end of test (250->65) 2-elimination after story writing (65->52) Then there were technical interview round, in my turn which was pretty late i introduce myself the he simply asked one question in electronics (i am from electronics) which i answered in a good way Rest queue are as follow 2-what is color code used in register? 3-what is transistor? 3-to find current in circuit which he draw in paper? 4-what is microprocessor? 5-8085 is processor or controller how many bit? In above question i got confused and can’t answer most of them correctly he then simply relax and asked how i feel and if i have any question? I simply said "sir i know my interview didn’t went write and i may not select on this performance so it would great if you could ask me more que and i could prove something" He simply took breath and asked 6-how microwave travel? 7-which modulation is used in dth or TV? 8-what is modulation used in optical fiber at your home end? 9-why use java not c?(i have mention java c and c++ in resume) 10-diff in c and c++? 11-swap two variable without using third variable?
