Amadeus Software Developer interview questions

This is an Online Assessment which has 2 questions. The first one was similar to the Projectile motion question where they gave some parameters like initial velocity, and angle and gave some unknowns to find the answer. The second question was a string-based dp question, I could not remember actually. None of the guys whoever has attempted this test solved that question. I felt it was difficult then.

Interview was done on campus. They asked to introduce myself then they asked about general Java questions. Then some DSA linkedlist concepts.I answered Java questions well but I fumble at linked list.
