Forgeahead Solutions Java Developer interview questions

I was interviewed for the role of Java developer and since it is in the COVID phase, so that was a telephonic interview. A total of two rounds. The HR, as well as the first round interviewer, were nice to have a conversation. Answered my queries as well. Can't say anything about the second round interviewer as he ended the interview way too quickly. The first round was a telephonic one and the other one was a video interview. I was able to clear the first round and in the second interview, the interviewer only asked me one question and after that, he said he was done with the interview. My answer was wrong but being done with the interview after just one question is too weird. First-round question s were based on Core Java and the second round question was on Spring Boot. Topics in the first round: Exception Handling, Serializable(Transient and Static keyword), Collection, Multithreading, working of HashMap, Arraylist vs LinkedList, Changes in Java 8. REST API.
