ADP Senior Software Engineer interview questions

Phone call screening - the HR forgot to send the e-mail for the on-line interview collaborator, kinda blamed me for not receiving the mail. Met 2 young folks - they're the interviewers - most obnoxious fellows i have ever come across. They just throw what questions they could find on the internet - not that they are aware of the CORRECT answers to those questions. Couple of things I noticed - they are not very organized, not sure what to ask interview - they pretty much asked all the topics under the sun, and funny thing is they won't even let you complete the answer - midway either would stop you or would ask completely different question. A 30 min screening round stretched to an irritating 60 + min - no sense of time and no respect for other's time as well. I wondered if they called to waste my time in the name of interview.

two technical interviews, one HR round. Each technical round lasted for sixty minutes.HR roudn lasted for twenty minutes. Technical they asked about thread,oops,exceptions,memory,Spring, IOC,Spring MVC,STRING,STRING BUFFER,collections,hashmap,linked list,array list,SQL queries,stored procedures.
