Microsoft Interview Experience | Set 46 (Onsite)

I had my onsite rounds with Microsoft.

There were 4 interviews.

Round 1. Given a circular buffer, write Get( ) and Post( ) methods . Get(n) should return the n characters in the string, if ‘n’ elements are not present, it should throw an exception. Put( string s) should put each of the characters of string s into the buffer without overwriting anything which hasn’t been read by Get()

Round 2 Longest common substring from 2 given strings. As I couldn’t give optimal solutions, asked me to write a strcmp(str1, str2) method

Round 3 Write a secure and safe strcpy( ) method . Asked me some theoretical questions about indexing and triggers for sql

Round 4 Write a program which generates XLS column numbers given the column number in decimal.
e.g.

Input Output
1        A
2        B
26      Z
27      AA
52      AZ
53      BA
... 

Good Luck to future interviewers
