Perfect. I have given multiple interviews in last few weeks. I came across maximum of the questions which you asked Akhil.
Thanks Abhilash. Keep this good work going.

[jatinsharma]

This video realised me how much should I need to prepare with my project for the first interview as a Java backend developer. Thank you for this session.

[nagamanjunath]

This is my first comment in any video... i actually had to do..This is just an awesome content.. so much technical and relevant for people looking out for a switch.. looking forward to learn more from you.🙂

[aakansha]

I saw your channel few days back and the content is really amazing, thank you for all your hardwork and keep making these types of videos

[VirajSalokhe]

Confidence booster video. ❤️.. Couldn't thank u more abhilash. I was down with confidence. Almost all things and concept which u guys discussed, I use in my daily routine, which I can not articulate. This video gave me deep insight about how to answer in interviews.. ✌️

[PapaFranciscoOk]

Im an experienced Software Developer but i needed some practice for an interview and this is by FAR the best video to get fresh again, what a great interaction you both had Abhilash and Akhil. Thanks thanks thanks and im glad that there are so many talented people coding out there.

[ahmetbcakici]

[codingshinobi]

[swagatpanda]

Top Quality Content,

[abhijeetpatil]

Thanks for making & sharing your views & experience with us. Whole heartedly appreciating all your efforts.

[oinohudsonobai]

Gentlemen, I have an interview on Thursday and I am using this to prepare for the interview. I am finding the content very helpful. I hope it helps me pass the interview. I’ll come back with the feedback in a few weeks’ time.

[mikesirpedro]

Regarding the question about "Bearer Tokens" I respectfully need to intervene: the concept of a "Bearer Token" has nothing to do with ownership, it is (as implied by the name) rather about "whoever presents, i.e. bears, this token is allowed to use it". The verb "to bear" means "to carry". So its much rather the opposite of "ownership", which would need to token to be labelled somehow with an identifier of its owner. Thank you.

[Creativethings]

Perfect video for recall overall on java spring microservices security and hibernate thanks abhilash 👌👌👌

[NDM]

Really found more deep concept rather than any class and Java video

[glaucogoca]

Thanks for sharing with us this interview. It's excellent to review things that we already know and learn new things. Congratulations. You are helping a lot of people.

[ramyasudhakonda]

Hi Abhilash, the way you explained list and it's inner logic it was most sensible. As we use lists just like that in coding. Thanks for the info. It will definitely change the way of my coding now .

[anuraggoyar]

1:03:30 we can also use ListIterator for adding elements while iterating
