nVIDIA

2nd company to visit our college. Very technical company...as well as very nice company. I loved black and green theme of their company.

This is the company which requires depth knowledge of C language n OS.

Depth bole to ekdam depth knowledge.....

Aptitude had 4 sections:

C , OS, data structures, quant section.( 70 questions).

From so many people only 16 cleared aptitude. I was d one in dat. Only four went through HR round. I was the one in dat. Only 2 cleared HR round. Unfortunately i wasnt in that.

Tech Interview (round 1);

1. You hav been scoring above 70% in all semesters xpt 4th.......any reason?

2. Write code for SUDOKU solver game(was mentioned in my resume)... He had given some conditions like blah blah blah...

3. Wat ll u choose? Single function with all code in it or many functions???

4. Where are variables stored??

I answered- Sir in memory....

Interviewer- and...??

I - memory???

Interviewer - where else??

I - sir memory.....with smile :D

5. What is stack, Q?

6. Register variables? When do v use it?

7. You do %4 with a number, that is you find the remainder of a number by dividing it with 4.

Which other operator and operand u can use to get the same remainder wid the given number?? ( I kno u dint understand this question :P :P).

See

y = x % 4

find an operator and operand to get "y" using "x"

i.e

y = x [operator] [operand]

Condition - instead of dividing it by 4 i can divide it by 8,16,32,64.... :P :P :P, Expression shud work for all :P

I asked can i use more than one operator, he replied: that wont be as efficient as compared to % operator :P :P.

I m damn sure that he must hav liked my answer :)
