Core Java- use of streams in java What happens if I try to access a variable(which is declared outside) inside a .forEach block? Is it possible? Yes/no -Why? Hashmap vs concurrent hashmap and it’s workings. How many threads can access a concurrent hashmap at a time? Is it possible to modify a array-list while iterating it? Is there a way to do it? Some coding questions on overriding and exception handling concepts

Algorithm question about Head, how to get first 10 highest numbers from streams of data coming from hundreds of sensors?
First part is uploading resume, and it will ask you why you wanna join IRAS. Second part was the coding. 2 theory, 8 output prediction and 2 debugging questions. Need 60% to pass the test. Third part was the feedback.
Springboot, microservices, controller, oracle
After the coding round, there were 2 more rounds, which were technical.
