I applied through a staffing agency and had a telephonic interview the next day.

They then called me for a face-to-face interview at their Jersey City office.

I completed a 30-minute written test. The questions were tough.

After that, I had two rounds of interviews.

The interviewer for the third round was absent, so they said I was done for the day.

After a few days, they called me for another face-to-face interview in their NYC office.

They explained it was for a different requirement with different teams.

I had two rounds of interviews that day.

They did not ask me any questions from Java, except for one Java program.

The questions were basically from Unix and database-related topics.

Again, the interviewer for my third round was unavailable.

That was it. I am still waiting for their feedback.

HashMap, String, Collections, Threads, etc.
