how was the interview
How was your interview?
Reject hua lgta hai reply nhi diya😂
one of the best interviews. Aswers are easy to remember. Well done.
Very informative video, I am a fresher, whatever the candidate explained I also know those concepts and can explain. I have applied for more than 1500+ companies but not a single company given me chance for an interview. I don't know how they are judging me without taking an interview. Please can you give some tips for me.
Customize your resume and cover letter for each job application. Highlight relevant skills and experiences that match the specific job requirements.
now a days companies are not preffering to hire a condidate and give training they are looking for trained even in the case of freshers, so learn and try to put some projects in your resume atleast a protfolio webpage. you can reffer youtube for that. this will work
Even I am experience and I have applying everyday near 100 company from one month but no one give me chance . What happening I don't know

this is best interview for revision
I have one year of experience, companies are not giving me a good hike. Just 20-30% for frontend roles . What skills should i learn on top of react and typescript to get a better hike?
50% wrong answers here , handling modal using overlay - it can easily handled using ref and event target , async await doesn't blocks synchronous code 😂 , dont use usecallback and use memo for all functions and value until it is required otherwise its gonna introduce extra complexity and delay in performance , major limitation of react is client side rendering and poor Seo. Btw bro is fully confident 😮 i appreciate that.
Great not even missed a single question
Very good interview clear my questions..
I think the process this candidate told for asyn function should be for sync function as async is non blocking and sync is a blocking function.

Bro was your explanation of promise vs async wait correct that in promise if we write console after the .then() function then it will print first?
Package kitane ka milega bhai
for this level of knowledge...
I just want to ask u from where did u learn JS and react in the Beginning days
I think when we optimize the application with useMemo in every export the memory of the application increases because it memoizes the every previous value. Correct me if I wrong.
17:20 what is controlled and uncontrolled components
a components without state called as uncontrolled component and a comoponent who use satate variable like usestate called as controlled components
One year of experience in frontend with good skills how much he can expect from a company...?
Subjective to skills.
If you can crack product based company like cred...
Expect around 20
If good service based company
Expect a 50% hike from current CTC
If good early startup.
Expect 100% hike on current CTC

Bro i am in final year noncs ,want to learn frontend . How should i proceed to get job ?
Hi bro.
If you don't know programming, learn basic very basics of js.
And try to solve atleast 100 problems on DSA.
Very basic question on array, string,LL,set,map easy ones no need to solve hard one.
Then proceed with HTML, CSS ,JS and react and make projects.
There is a lot to it. Cannot write everything here but I am making a beginner Frontend Development roadmap.
PS: I am also a non cs guy :)
@@dev_insight_official thank you for help ✌️
Editor please add a beep when ever he says basically
Can I train you.one to one .fees also pay sir.

Awesome interview, cover all the required stuff as js dev should know thanks
An interviewer didn't let candidate explain properly as he was saying hm hm ok ok a lot in between, which led to leave this video.
Kidos to developer 👍🏻👍🏻

Worked in two company and still can't explain what happens in the runtime when executing a promise and async and await.
He could have started with the difference between them in brower runtime and nodejs runtime.
