Zerebral IT Solutions Associate Software Developer interview questions

The role is basically Software developer with ML knowledge. But I have only conceptual knowledge of ml then they taken entire interview on Java core as well advance focused on deep knowledge of each and every concept. Answered almost 90-95 % questions with complete accuracy but they want people with ML hands on. they waited us for HR interview for 2.5 hours after clearing technical round, after waiting they said you are not having next round. They might got what they want so, they rejected me.
