Salesforce Associate Technical Support Engineer interview questions

First round - Online Hacker rank round with some technical(Java & Data Structures MCQ) and aptitude MCQ's along with 2 coding questions (Arrays & Strings). Second round - Online versant round (English communication was tested) I cleared the above 2 rounds and for the 3rd and 4th rounds we were asked to come to Chennai for F2F Interview. Third round - Asked few technical question from resume (Java, OOPS, DBMS) and was asked to write a SQL query and a few behavioral questions. There were 2 panel members and this round went on very smooth. Fourth round - This round was considered to be the final round and was a Hiring manager round. The lady who interviewed me was very rude. She seemed to be very disinterested and was engaged in other works while I was answering. Very general questions were asked. Since this is a support role questions relating to dealing a customer, scenarios and such were asked. I managed to answer inspite of being frustrated with the lady. Finally after waiting for 4 hours, I was informed that I was not selected.
