Chubb Software Engineer interview questions

I solved all the questions properly but I didn't get selected may be bcz I passed private var as __age__but it must be __age But implemention was fine and it was properly implemented I asked him in last that let me update that var he said it's fine no need to worry and latter to hr he told he didnot implemented multiple inheritance. Very worst interviewer. Hr is very much helpful person, thanks to him Abhilash the hr, very calm and responsible person
