Hi
Seriously this is the most easiest interview ever seen for 5+ experienced candidate
Thank you for sharing this content, good luck for the next interviews !
Thanks for watching!
Nice 👍 helps us bro keep sharing guys
Questions are very easy for 5+. Still candidate was not able to answer questions we require on daily basis. Try hard and all the best 👍🏼
ist question set the tone.Plus the exception question was easy.But its ok My ist interveiw after many years did one dreadful mistake of saying hasmap when duplicate keys are inserted it doesnot allow it(true)because of hash function/equals contract or whatever explanation one can give + value is replaced with new value(i really tanked this value replacing thing).I gave partial correct answer.My point it can happen to any of us sometimes..Keep practicing we shall move forward.
JavaTpoint open kar ke bhi Ans ni de pa ra basic questions ka...
We can have two methods with same name but with different parameters which is Method overloading
Yes buddy, you are correct.
What is that question copy on arraylist?
👍
nice interview. interview taking person is so professional and candidate also.
Thank you
The interviewer is smart, fooled the candidate at so many places :
1. Is Throwable a class ? candidate with confidence - YES
2. Cloneable , so the candidate was fooled into saying its a functional interface but its a Marker Interface.
3. On asking how to use Comparator Comparable, the Candidate kept beating about the bush, could have straightway answered Collections.sort(employees) for comparable and Collections.sort(employees, (e1,e2) -> {return e1.salary - e2.salary;})
4. Exception overriding in child class method is possible if there is inheritance in the exceptions being used.
5.
This is the easiest interview I've seen for a 5+ yrs experienced person. I think you were just confused while answering most of the questions. Just keep on attending interviews, you'll eventually improve.
If the candidate is not able to answer easy questions, then the level of further questions will be decreases so the chances of selection of candidate.
@@javainterviewbuddy567 Yeah totally agreed. My comment was actually meant for the candidate. I think I mistaken you as the candidate😀
@@javainterviewbuddy567 wow nice idea 💡
First question makes a impression as per my experience and he spoiled it.
I also think the same, First answer can make the difference.
It's looks like freshers interview

Did this candidate have really experience of 5year ?? Seems like 1.5 year
Unfortunatly
Exactly..
I can bet he is cheating/have someone on his side saying him answer, he is able to tell what is lambda function but he doesn’t know it is used in Stream APIs while writing programs.
hello ..Do you hiring 2-3 yrs experience guy right now.If so please let me know.
Okay
aise interviewers hme nhi milte !!! sala ek question me skip krne ka nhi tha, means fresher level pe tha !!! and bhai plz work on your communication as well as technical skills , like "NOT REALLY" tone bhut odd lg rha yha pe !!!
jese jawab honge wese hi questions honge, agar simple question ka hi answer naa mile to tough kyu hi punche
@@javainterviewbuddy567 yar ye bat bi shi lg rhi , cz mphsis me 1.5 hours tk interview chla and stil no response
Koi early joiner mil gya unhe
He was selected?
Yes, but I think not went through next round.
Are u cleared this round??
Unfortunately Not. :(
It was really 5+ years experience because I have 1.5 years experience and I knew all the answers you ask.
Doing great buddy 👍❤️
Thanks a ton. I am glad , it is helpful for your interview preparation, all the very best.
Yes 1 or 10 yrs the base or core concepts are same for all But they will ask more depth for more experienced people. that is the main difference..
Bro nothing like that it's technical round he will be having another one round, coding and adv core java
..5.6years seriously ..
Yes.
He doesn't sound like 5+
Who is hee??
He Doesn't even know the basic concepts...😶
Its Unfortunate. Nowadays, most of the things are available with just a Google search.
Ye kya candidate ko knowledge nhi h
hota hai aisa bhi
