IBM Software Engineer interview questions

They asked about the questions related to engineering. They asked all the basics of computer languages . They even asked about experience and also introduction about ourselves. After everything they offered a job which was good at that moment I dint accept it.. It helped me to gain some experience.

They first gave me a coding interview. The coding interview had 3 questions. The questions were quite simple and mostly required a simple math trick to solve. I passed all test cases but never got a call back...
