I am a older mom with 2 kids, changing my career to a full stack developer. It is really hard for me to squeeze time learning all the technologies and compete with those young talents, but I am trying. Thank you so much for your videos, very self-explanatory! I just purchased your Udemy class for support! I will definitely let you know if I finally land a job~
Hi sir from watching your videos and following your advice today I got my new job thank you very much sir In the interview almost all questions are asked that you taught only
Hi Happy, first i would like to thanks for efforts in making vedios which are helping thousands of people. I had 4 years as a .Net developer but when I started giving interviews i felt like am zero. But then i started watching your videos and now i have 4 offers and one in pipeline, whatever questions i used to get in interviews 98% of them were on ur channel. It helped me lot in my career and i have recommended it all my colleagues. Thanks a lot Happy… just like ur name says u made so many peoples life Happy 😊 all the best for ur channel and you ❤
IS IT RECESSION??? Many candidates ask me. Sir, right now the market is not good. What should I do? And 100 times I said that. Don't let your fate be decided by circumstances. Follow your goals and grow more and more. Even if recession or firing is real??? Are you waiting for your company to fire you? Go give some interviews and be ready for any situation. Crack the interview and don't accept the offer. Simple without any harm. (But the day you will crack the interview, your thinking will change positively) But please DON'T GIVE EXCUSES and DON'T SPREAD NEGATIVITY.
Thank you for this valuable course! The questions are very practical-I encountered several in my first round of phone interviews. I believe every front-end developer should master these Q&A for good luck to favor them.
That's the spirit... You remind me of myself. I was never a good interview person, but giving up was never an option. Also, you remind me of the "Unbroken" movie plank scene. Hats off, and all the best for your interviews...
@@vamshikrishna6001 keep notice as 30-60 days, in HR round you can request for increase in notice period or decrease in notice period from current company. try updating ur profile and resume just make small changes so that your profile gets on top and in actively searching for jobs. Just small change is also enough and make that changes after 9pm night so morning when HR’s search u ll be on top. These are some tips for getting calls. Hope it helps. I felt naukari platform is good for job search. Never stop giving interviews, i gave more-than 15 interviews to get a job so keep going. More interviews you attend more confidence and more knowledge u will gain. I learned so many of them from @interviewhappy and it worked for me All the best 👍🏻
❤ from TamilNadu.. I got an offer from HCL for Fullstack role (DotNet + ReactJs) Your videos are very very very helpful to clear the interviews. Thank you so so so much for you.... 🙏🙏🙏🙏🙏☺☺☺ Keep posting, keep supporting...

I'm a full stack dotnet developer. The way you explained all the concepts answered more than just the questions i had in my mind initially. Great work 😄👍
Thank you so much for your amazing interview prep videos! Thanks to your content, I was able to crack my interview and secure a 65% hike in my salary! Your guidance and tips were invaluable. Keep up the great work!
This amazing accomplishment is just one step on your journey. This career move is a perfect fit for you, I'm so excited on your behalf. It would be nice if you could post your package and firm name to motivate others; but, if you prefer to keep it private, that is fine.
Hello sir... Few days ago I came across your video and I saw this video , now I am placed in a company, All because of this REACT ❤️🔥!! THANK YOU SIR🔥
You'll be successful wherever you go, best wishes for this new job opportunity. Congrats on this next step in your career. It would be nice if you could post your package and firm name to motivate others; but, if you prefer to keep it private, that is fine.
Hi Sir, Thank you so much.....🙏🙏🙏 I attended the more than 15 interviews but i am not clear. Now I got an offer from MNC Company for React JS Developer role. Your videos are very useful to clear the interviews. Please keep going on latest technologies.... We are all support you Once again Thank you so much sir!!! 🙏🙏🙏
Good collection of questions and you have explained in a nice way. I as a beginner of React, wanted to thank you for all this. Just had a question: In Route chapter - in place of "element" attribute inside tag, you have mentioned "Component", will it work or need to change to element?
Great work sir! Can you please make a similar video for React Native Interview Questions? I couldn't find a proper video for react native on youtube.There might be many students like me facing the similar issue. Please help us out!!!🥺
Thank you for this video. It is good and easy to understand for revision as I am still giving interviews as fresher. Please bring a Redux interview video. Interviewers have increased the bar and ask questions that a 1-2 year experience will bring on the table. Thank you.
Hi, thanks a lot for this video, this video helped me to answer a lot of questions in interview, some suggestions would be to add exception handling topic like 'error boundaries' and some js prerequisites like map , filter , prototype, closure ,benefits of immutable state in react. 🙏
Thank you very much sir this video helped me also and I recommend this video for most of my friends please keep going and create the content like this 😊
Really this video is awesome. You put your all efforts in this video. It will help each and every developers and help to getting the job. Thank you sir for make us batter and strong in react. I think i will get the job soon after watch this video and revise it 2 or 3 time. Again thank you so much sir❤.

Thank you mam.
I am a older mom with 2 kids, changing my career to a full stack developer. It is really hard for me to squeeze time learning all the technologies and compete with those young talents, but I am trying. Thank you so much for your videos, very self-explanatory! I just purchased your Udemy class for support! I will definitely let you know if I finally land a job~
All the best 👍

Great React interview questions! 👍 Hoping for a follow-up with 100 Node.js questions. Your content is invaluable for developers! 🚀
Hi Happy, first i would like to thanks for efforts in making vedios which are helping thousands of people. I had 4 years as a .Net developer but when I started giving interviews i felt like am zero. But then i started watching your videos and now i have 4 offers and one in pipeline, whatever questions i used to get in interviews 98% of them were on ur channel. It helped me lot in my career and i have recommended it all my colleagues. Thanks a lot Happy… just like ur name says u made so many peoples life Happy 😊 all the best for ur channel and you ❤
hi muje thoda guide karo na ki apko scenario based coding questions puche the kya
@@jayeshmahajan4213yes in some companies not in all
IS IT RECESSION???
Many candidates ask me.
Sir, right now the market is not good. What should I do?
And 100 times I said that.
Don't let your fate be decided by circumstances.
Follow your goals and grow more and more.
Even if recession or firing is real???
Are you waiting for your company to fire you?
Go give some interviews and be ready for any situation.
Crack the interview and don't accept the offer. Simple without any harm.
(But the day you will crack the interview, your thinking will change positively)
But please DON'T GIVE EXCUSES and DON'T SPREAD NEGATIVITY.
Wish u share ur interview experiences
@@jayeshmahajan4213 yes in some companies
Thank you for this valuable course! The questions are very practical-I encountered several in my first round of phone interviews. I believe every front-end developer should master these Q&A for good luck to favor them.
Attempted 12 interviews in 2 months, for Senior frontend dev , now I am here lets see how my other interviews go
That's the spirit...
You remind me of myself. I was never a good interview person, but giving up was never an option.
Also, you remind me of the "Unbroken" movie plank scene.
Hats off, and all the best for your interviews...
Nice spirit! Wish u share ur interview experiences. We are not even getting calls. Thanks for info. Please do analyze if possible, any issue once.
@@interviewhappy
Please upload Python interview questions Sir 🙏🤝
Where are you from
And how r u approaching companies
@@vamshikrishna6001 keep notice as 30-60 days, in HR round you can request for increase in notice period or decrease in notice period from current company. try updating ur profile and resume just make small changes so that your profile gets on top and in actively searching for jobs. Just small change is also enough and make that changes after 9pm night so morning when HR’s search u ll be on top.
These are some tips for getting calls.
Hope it helps.
I felt naukari platform is good for job search.
Never stop giving interviews, i gave more-than 15 interviews to get a job so keep going. More interviews you attend more confidence and more knowledge u will gain.
I learned so many of them from @interviewhappy and it worked for me
All the best 👍🏻
