Lumen Senior Software Developer interview questions

I went through through referral for the post of java Developer having 2.4 years of exp.. First they took written test consisting of 20 MCQ 1 for correct answer and -0.25 for wrong answer. Along with that 2 programming questions. 1. Find the series of Fibonacci number by giving input as n where n will be no. elements need to be displayed from that list. 2 Algorithm to write Arrays Sorting. This wasn't Elimination round but on the basis of written only they will ask in Interview. Tyy to write program as clearly as possible and add comments if possible. And after the written i was interview almost 50 minutes and there also he asked me too many programs. There he wanted to check my logic. Initially he asked me basic core java questions then went deep asking modifications of Java 7 to Java8. Please mentions your skill properly in resume.
