Invesco Java Lead interview questions

Called by an consultency .It has 2 technical rounds and 1hr round.The questions are not too difficult but need a good solution for what they are asking They have shifts so be care full to ask the timings before joining and check is the position has any support role becasue though they mentioned it as Jva Lead when I discussed they have some support role .. The questions are average but they did not clear the second round when I asked for the feedback there was no proper answer.
