Capgemini Mysql Developer/Administrator interview questions

L1 and L2 interview. Focused on dB architecture, understanding of layers within it and the feature upgrades on MySQL versions. HR is not good. They call you in the nights around 11PM and asks you for details. Never picks our calls but would call only if they want to speak for any information. Recruiter says, you are selected and will get a call from HR. HR never comes into picture.
