Google Mini Interview

My friend submitted my resume and I soon got an e-mail from one of their recruiters. Today I had an interview with her and had the following questions asked:

Please rate the following from:

1-3 I have read and studied it, but wouldn't feel comfortable using it
4-6 I feel comfortable using it in my routine work
7-9 I could teach others
10 I'm an industry expert in this topic

Then she asked me to rate things like C, C++, Java, SQL, Python, Shell coding, Linux-specific coding, UNIX-specific coding, Mac-specific coding, testing web sites, and writing automation.

Finally, based on those results she asked me:

C++
1. How would you go about removing an array that was created with the new operator from memory?

Java
2. What is the difference between a string and a string buffer?

General Coding
3. What is the average runtime for the quicksort and what is its worst runtime?


I'll find out if I get an interview within a week or so!
