I gave my resume in career fair in October. In November end I got a mail asking for my available dates. I gave my first interview in December. It was a phone interview and lasted for one hour. I was asked the basics of Relational Db(some queries), Distributed Systems, Java(overloading and overriding, anonymous classes, static fields etc) and Web services(Http, RPC, xml etc). It went well. Then after 15 days I got a mail saying I cleared the first round. The next round was with managers. There I was asked basics of cloud and java. Then about parametrized queries, cross platform scripting etc. I was not very confident with this round. After 15 days I got a mail which made my day. I got through Salesforce.com :)
