Oracle | Application Developer

Hi everyone,
Experience : 1.8 Years of Experience as SDE1 at Verizon(10 LPA) with career gap of 6 months.
I have attended for the onsite interview at Oracle Hyderabad office on July 13th. There were total 3 rounds.

Round 1: DSA and SQL with HR questions

1.easy level SQL question finding employee with highest salry in each department.
2.DSA question(medium) N horses problem just like N queen problem.
3.DSA question( medium) if n is add then n=3n+1 if n is even n=n/2. Rank of number n is how many steps it will take so that given n will become 4.(ex: n=10 10-> 5->16->8->4 total 4 steps). Given a range 1 to N you need find number with maximum rank.
4.2more easy questions on DSA which I dont remember exactly. Those questions are related to array solved by using frequency count.
5.Few Hr questions.

Round 2: DSA

1.Implementation of sorted circular singly linked list. Ask me to write functions for insertion,deletion and searching.
2.Printing pyramid.
1
1 2 1
1 3 4 3 1
1 4 7 8 7 4 1
Round 3: DSA

1.Find next greater element using stack
2.merge sort implementation.
3.question on array used by solving prefix sum(dont remember the exact ques).

After these 3 rounds of interview,Interviewer said that I have cleared all 3 rounds and I will get call from HR for the final round of interview which will conducted by their VP which will happen in 4 or 5 days. But still interview is not scheduled yet. HR told me that interview will happen in this week. So anyone who appeared for this type of interview in Oracle help me by saying what to prepare for this interview. And also please let me know how much compensation should I expect??
