I was initially contacted by a recruiter, who was very responsive to my questions, and instructed to take an initial debugging test. The test was a multiple choice quiz debugging C code. The code itself wasn't hard to debug, but for multiple questions I didn't know if I could assume things such as if the arguments given were always accurate or if memory allocation always succeeded. I tried to use context clues to determine what I should assume but whether the code checked it's inputs or checked for a successful memory allocation varied from question to question and therefore there were multiple questions where I could have justifiably argued that there were multiple answers for the same question. After I took the quiz I very politely emailed the recruiter to tell her I felt good about the test, but that the quiz was ambiguous because it didn't clarify what we were allowed to assume. A few days later all I received was a boiler plate email telling me that I would not be moving forward.
