    Interview

    I was called to have an interview for a student position, I'v had 3 interviews there, the first 2 are technical interviews and the third is HR interview. I felt the interviewers were kind and supportive.
    In the first interview, the first question was to convert a number from Hexa to decimal, then they told me to write it down. Then they gave me some classes in C++ and asked me to write a function that uses the types and methods of the classes.
    Second interview, first they asked me to find a recursive algorithm that reverses a list. Then they asked me write a function that given 2 strings I need to return the index of the first letter in string1 that is also found in string2, in a minimal complexity. Third question was a "riddle", how to measure 9 minutes using a 4 and 7 minute hourglass. There was another question, about pines and gates, I forgot the specific details.
