Phone screen ask to write a string manipulation function in Java. Don't remember exact problem. But it wasn't hard. The coding required me to show familiarity with coding (need to code fast), programming language, and some corner case handling.

basically the test was a high school, entry level modest C set of 3-5 lines long questions, all in almost K&R meant to test if you knew that local variables are not initialized, to see if a for goes beyond nSize - 1, that being given a pointer you can access it using an array and other things of this sort. responses were automatically grilled (just like dmv office) and the so called "technical" recruiter was apparently computer illiterate
