Nuance interview questions

You go through a recruiter hired by the company and if you get an interview you get the job, very easy.

I had 7 interviews and no offer, 2 phone 5 onsite. I felt like I did really well in the interview, I answered all the questions correctly but they decided to hire someone with more experience than me even though it was an entry level job. The interview itself was a bit unprofessional and unorganized, they kept repeating the same questions and one of the interviewers kept on answering the phone while I was being interviewed. The interview is pretty easy no trick questions. each applicant also gets a sheet of questions they have to answer which consists of multiple choice questions. These are the questions that I got: What is MVC?What is a static variable? How does garbage collection work and list it's pros and cons? Multiple choice question on bit manipulation (& and |) What is polymorphism? What is a singleton and how would you implement it and how would a client access it? Which of the two are part of OO: inheritance, encapsulation or recursion? A written question on tic-tac-to.What is a use-case? what is a deadlock? A question on recursion you have to give the output. A coding question on the whiteboard you have to read a file and see how many instances of a string there are in that file. Really nothing is hard just understand the fundamentals of programming and basic concepts of sw engineering.
