Simplify3x Senior Java Developer interview questions

i got a call from simplyfy3x from indeed in same day the interview was scheduled i just had 4 hours time between the call and interview , i don't have preparation but i have given . interviewer name is Praveen , due to cyclone there is turbulence in network but we didn't stop the interview proceeded without it video over a zoom call . i have tried my level best . interviewer sound so good , if i get offer i would like to work under him .thank you . waiting for result i am impressed with interviewer, because most of people ask theory on java which don't use daily in coding but he asked what we use daily in coding.
