Qualcomm Interview Experience: Second Round – Technical (Skype)
It was skype interview. It started with the general introduction and brief discussion on projects. Then they asked me to write code (any language) to check if two given strings are Anagram of each other or not, characters can be in upper case and lower case.
Solution: You can find the complete program to check whether Two Strings are Anagram or not in C.
They asked me some questions on computer architecture. Most of the questions were related to memories especially concepts related to the cache memory.
After asking some theoretical question, they asked me one numerical question. As per I remember, the question was like below.
There is a system with the cache size of 128K. It uses 32bit for addressing. It has 8 way set associative cache. The block/line Size is 64B. Calculate the tag Size in terms of the number of bits.
Then asked me to write matrix multiplication program.
There are three matrix as a[M][N], b[N][L] and c[M][L]. All matrices store integer values. The size of the matrix as per value assigned to M=256. N= 256 and L= 128. Task is to write the code to find the matrix multiplication of matrices and b (c=a*b).
After writing the above code, using above data (previous cache question) they asked me to calculate miss rate for the matrices.
You can find other Qualcomm interview questions on CSEStack shared by other candidates.
