Domande di colloquio per Senior Java Developer presso Securonix

Faced just one round of interview. Went for Senior level Java developer interview 1) 2 Interfaces in java has a method named m1() and one class implements both the interfaces. Which interface method will get called while calling the m1() method. (I wrote the question as is) - Illogical question 2) What if I add keyword abstract for interface 3) How will you read a huge file from disk using multiple threads - Not possible but seems the interviewer had some answer in his mind for this question 4) Given an array count occurrence of all elements in this array 5) Given a bus. 40% seats are reserved for ladies, tell the logic to book seats such that no lady sits adjacent to men. With some more conditions.
