How i've failed programming challenge on Turing.com
HTML-код
- Опубликовано: 11 янв 2023
- Thats how its done when there is no preparation and warm up.
1. I tried to copy the template to VSCode using Ctrl+C - Ctr+V and just messed up the template.
2. Incorrectly read the task. It should do reverse() not sort().
3. Did too little sample tests (thats why in showed OK inspite of major logical mistake).
4. I didn't do any warmups for a month. In fact i haven't coded in a while - thats why i kept forgetting regex.
5. And all that lead to complete lack of time for a second challange.
And finally - when recording (or programming when someone watching) you make a lot more mistakes. Thats how i failed toptal.com last year (i did passed online tests), but failed really simple one on an interview.
So im gonna continue filming my attempts at taking tests - i hope it is a good practice for live interviews.
I love the fact that you had the courage to open a real test, I am also in the Coding Challenge Phase too, I am just inspired. Good work Sir
I have done the coding challenges more than ten times and have passed, with different emails.
@@kevinobuya6013same question every time ?
@@kevinobuya6013 are you hired right now?
@@kevinobuya6013 do you teach as well ? i want to pass as well,
@@kevinobuya6013 Hi there I want to pass this coding and I am really working hard please can you give this question so will practice and will be able to clear it
Respect for going live with this, very nice. Keep it up.
Thanks!
@@IgorKravets81 Have you passed the test now? You got job through Turing?
Thanks for sharing! I really needed it.
Thank you sir! I appriciate your effort. I learned a lot!
Thank you for posting this! I also made the mistake of underestimating it and just going in without any practice for months.
Next time will be much easier!
so its not a rush? ive been getting emails from turing encouraging me to take test? because it think its better to practice for a while for me too ..
It was really fun. Anger, depression, hate and hope all in one video. Good luck next time :)
Yo vi tu video ahora, y te agradezco mucho por compartir este sensacional video 🚀🚀🚀
Im glad it helped somehow ) thanks!
Best solution with O(n) would be two pointer technique and sliding window..for Problem one..but taking real test live was really great
function reverseOnlyLetters(s: string): string {
let result: string[] = s.split("")
let currPoint1Index = 0
let currPoint2Index = s.length - 1
while (currPoint1Index < currPoint2Index) {
if (!/^[a-zA-Z]$/.test(s[currPoint1Index])) {
currPoint1Index += 1
} else if (!/^[a-zA-Z]$/.test(s[currPoint2Index])) {
currPoint2Index -= 1
} else {
const temp = result[currPoint1Index]
result[currPoint1Index] = result[currPoint2Index]
result[currPoint2Index] = temp
currPoint1Index += 1
currPoint2Index -= 1
}
}
return result.join("")
}
Thanks for the hint
@@shubhamkashyap3762i agree with this. But it’s kinda ambiguous if the char at the i position is a letter and the character at the j position isn’t. I’m sure we ignore the j position but the for the i position should we move on or try to reverse it with the next non letter j position
Very nice video.
The answer for me was use ascii of every number and ascii str1 - ascii str2 and you will find the letrero and convert to letter
Informative
29:00 "Yeah I am not gonna make it in two minutes" cracked me up lmao but thanks for the video tho
You did your best bro! I have been in that scope before
Thanks. Still I should have been more prepared )
@@IgorKravets81 Of course especially in time management
@@IgorKravets81 I have a question dear friend and that question is do they ask you to open the camera? how can i prepare for it?
@@DavidTheWiseOne No they did not ask for the camera, at least when I took the test...
Brave man than 90 percent ty
You did well bro.
Thanks ) ☺️
You did well
Thank you for your support!
i think you can just add these string characters reversely into array and then just convert it into string .This is an easy method
let str='ab-cd'
let newStr=[]
for (let i = 0, j = str.length - 1; i < str.length; i++, j--) {
newStr[j] = str[i];
}
// Convert the array back to a string
newStr = newStr.join('');
console.log(newStr)
Just need two pointer and check variables for each pointer, right?
I failed the challenge too, I felt my first question didn't give me enough information or explanation to solve it, so I by passed and solved the second challenge in less than 5 minutes. Even though I failed the challenge, the tiring profile opened for me. Am just going to fill the profile while waiting for a response
So what happened, did you make it?
Wow. You did a good job. The only thing I think you missed was you used an array sort method instead of an array reverse method, on the array with only letters.
Anyways. I never would have solved this honestly. 😂
Can you tell me what further goes after passing skill assessment ?
In coding test what they ask basically?
I passed those, but when i tried the "practical nodejs challenge" I failed because the question was written in such a way that it was hard to understand what the person tried to say.
"the product_list payload contains a few parameters and all should be validated, and throws TypeError / RangeError / InvalidInputError to the caller if anything does not meet the specification"
What exception type for what type of error? Was the function supposed to return a "product_list" ? Why, if it's asking for a single product to be "validated"?
Insanely bad
Yeah, sounds like fun. I guess you have to get used to those tests to get comfortable. Or just work at some company where humans lead the interview right from the start
did you manage to complete the practical challenge?
i faced the same problem, I could not understand the question.
@@pratikgohil7821 nope. I deleted my account on turing as well.
@@pratikgohil7821hey bro, I also passed the coding challenge but failed the Node.js practical challenge, the question was very confusing. I do not want to complete my profile yet until I am through with all practical challenges, what is the next step after completing the practical challenge?
you can not copy and paste in the turing editor.. something important to note
Thanks 😂😂
disable javascript, copy and paste, enable javascript
you will i guess have to reload the page when you disable JS@@kravetzpm
Very good coders fail these tests all the time because of anxiety, unclear questions or just a poor editor like the one on Turing. It does not mean you are stupid.
First time I did one I was so angry because I’m a frontend dev and did not expect to be asked to write someone stupid palindrome algo lol 😂
A better way to test is to ask to solve common problems you will encounter as a developer.
I agree with you. I have a computer science degree and I work as a frontend too. I've practiced a lot of algorithms and data structures problems since I've been in university but it still hard to take a problem like the second one if you have not been practicing recently. Also it is not correlated for a frontend position.
@@bozzistef also at current job I sometimes get stuck on the problem even without time pressure. For example with some weird css someone left me to figure out. Doesn't mean I'm stupid. Eventually I solve it and get better.
I thought I was the only one with this same opinion. I’ve been a front end for four years now and I was thinking I was the only stupid front end developer that couldn’t write those algos seamlessly.
Are you allowed to switch tabs in turing tests? Isn't your screen recorded?
Same thing happened to me. I know I am good at this, but the clock ticking gets me nervous. I wonder if Igor passed the test now. Its been 3 months.
I started to search a for a job a conventional way - via direct offers from companies. I did several test tasks and got four approvals during this period. I do work now, but searching for a new job with higher salary )
@@IgorKravets81 Kudos to you. I am preparing for the Turing test by learning algos. Looking forward to get some work.
@@usamakr best of luck, let me know how it goes!
@@IgorKravets81 Passed it this time. Yippee !!!!
@@usamakr great job!! Please share how the actual work goes.

the environment is very weird... the output is kind of hidden
I have thesame concerns. It thing it’s unnecessarily complicated. Did you get to retake it ?
No it was not hidden. I just didn't see it at first. Because I took training test a couple of weeks ago so I completely forgot where to look for console output
@@adeyvincent3570 no I did not retake it yet. I got employed by conventional old style way by applying to particular company
Are you allowed to google during the test?
I should hope so. Although I noticed the page seemed to react to switching tabs. Possibly it was taking notice on distractions.
@@IgorKravets81 true.. I think it is monitored
It's possible but you only have 30 minutes for two problems. I don't think that's good time management. That's why you have to master DSA.
After completion of coding challenge what is the next step?
In my case: post a video of a failure ) although couple of years ago I passed similar test for toptal.com site and the next step was one more similar test, but online via a zoom call. I didn't pass that one, so I don't know what are steps beyond that.
bro this turing bootcamp is free?
I'm going to take it , any advice?
Yeah like I said: don't try to copy paste code - might screw up template. 2. Warm up - make sure you've been programming recently and remember basics. 3. Get to know where debug output goes ) 4. Make a lot of debug output to avoid stupid mistakes. 5. Make sure you fully understood the task. 6. Test resulting code against as many border cases as possible
and film it )
@@IgorKravets81 do they require filming a video passing the test ?
test =(str)=> {
return str.split("").reverse().join().replaceAll(',',"");
}
let res = test("ab-cd");
console.log(res)
Is it allowed to google during test ?
I'm not sure if it is forbidden. But you could switch to another window during the process. Maybe it is logged somehow though
My solution would have been to remove the non letters and store them in a hash map with their indexes
Then reverse the string and reinsert them using splice()
You could just do this if you want to make it step by step easy, reverse the string, and loop Trough the first string and if its a letter replace its index with the reverse string index.
Also what im thinking
But insert using splice() take O(N) time.
So, ultimately, it becomes O(N^2)
Do you get another chance to clear the test?
Yes, after several months. I don't remember how much now. I think it is shown at the end of the video
yes, after 3 months
Did you take another try??
Not yet. I got a fulltime job at a company
@IgorKravets81 very nice. Could you make a video about your current status/job role/update
@@AlamKhan-yt9wd I don't think there is anything valuable left to share... Although I went through quite a lot of interviews and also screwed up a bunch of them. But all the advice I possibly could give on those - are already covered on RUclips extensively. I think the best advice there is to take every interview you can - gain experience on passing them
@@IgorKravets81 I tried the practice challenge, the question was not difficult, but when I try to run tests, it failed and it showed errors some places but I never understand why. I would prefer using IDE. I mean the get method of an arraylist yielded an error. There were many errros. it was very sad so I am hesitating to start the code challenge.
How many questions does this have?
I think there are two. Frankly I don't know )
@@IgorKravets81 okay, that's not too bad!
Then how many test do you have to take?
This env is not confortable at all. Explanation needs constrains too. The challange here is keep your stress out😅
Can anyone confirm that Turing is a legit way to find jobs? I passed a coding challenge and a few tech stack tests, but failed the practical challenge because their IDE is utterly slow and lacks autocomplete.
And I'm also starting to doubt about the quality of this service - first of all, it's kind of silly that they advertise about "U.S. companies" jobs like every developer on the planet dreams to work for a USA company, secondly their quizzes are just some low quality garbage written by a junior dev, and moreover the questions often have nothing to do with the technology itself but rather with some popular 3rd-party library.
Also, RUclips is full of positive reviews published on their own channel instead of reviews from real people. that's what bugs me as well.
We're legit!! Can't wait to have you
@@millennyfeng9502 nah, you can't have cause I'm from a banned country
it's legit but passing the tests may be completely ignored by them. Best way is likely getting into contact with some from there to have real chances.
@@rekcahY Like even after passing all the rounds , do we have to nudge them for reminder? How was your experience can you share. Thanks
