Sabre Senior Java Developer interview questions

I applied through a placement firm for a contract to hire position. Appeared in person, one round of technical interview followed by a manager catchup. I started within a week.

At first got a call from HR asking for my availability and scheduled a telephonic interview. After 3-4 days got response from HR saying that he got very good feedback from telephonic interview & want to setup a onsite interview or Skype/video call based on my comfort. I chose for on-site. Onsite interview is scheduled for 3 hrs and with 3 members separately. One from Business related, one from technical team and another is also a technical. Overall, it's a very good experience. Because, the HR whom I am talking to is very quick in giving response. He gave me best support to schedule interviews based on my comfort. I was informed that I am selected but yet to get an offer from them. They said they will be sending an offer to me this week.
