Dunyoda ko’zga ko’rinmaydigan, lekin insoniyat rivojiga o’z hissasini qo’shuvchi insonlar bor. Huddi shunday algoritmlar ham mavjud. Masalan Kernighan algoritmi.
Yuqorida bit manipulation orqali tekshiriladigan klassik yechim va Kernighan algoritmi orqali optimalroq yechim berilgan.
Bir soniyada ishlaydigan kod uchun bu narsalarning qizig’i yo’q, ammo NP-hard masalalarda va bir necha milliard va trillionlab amallar bajariladgan dasturlarda oddiy qilib aytganda it makes the difference! Ba’zida dastur ishini 0.5% ga tezlashtirish katta 💸 degani, unutmang!

Pavel Durov
there are no complex tasks in this world—only many small ones that look scary when combined. Split a big task into smaller parts, organize them in the right sequence—and “you’ll get through”
This is the mindset everyone should have. I’ve met so many people who are afraid to build their careers or change jobs because they fear the challenges of a new role. That’s ridiculous. Don’t be like them! Keep moving forward—there’s no reason to fear such small things. Remember, WE ONLY LIVE ONCE!

Yandex Interview Stages
Topshirayotgan pozitsiyangiz va qaysi usul bilan taklif qilinganiga qarab o'zgarishlar bo'lishi mumkin.
➡️ Intern va Junior levellarga odatda 1-3 ta coding (problem solving) seksiyalari bo'ladi.
➡️ Middle/Middle+ levelga qo'shimcha System Design qo'shiladi.
➡️ Senior/Senior+ levelga Deep Experience Discussion (o'zim nom berdim) - avvalgi ishlarda qilingan projectlar va ulardagi asosiy qilingan ishlarni in detail gaplashiladi, albatta NDA ni buzmagan holda
➡️ Finals: Bulardan o'tib bo'lgandan keyin, Team Matching (finals deb nomlashadi) bo'ladi (menda 5 ta bo'ldi). Har biri 45 daqiqadan. Bunda team va siz bir biringizni tanlashingiz kerak. Shundan so'nggina offer beriladi va negotiationlar boshlanadi.
What you can expect
✔️ Remote/Hybrid/In-office usulda ishlash. Ishlash turini istalgan vaqt kelishib o'zgartirsa bo'ladi, juda oson. Ofis 24/7 ochiq
✔️ Ish sifatini tushirmagan holda travel qilib ishlash.
✔️ Official ish va trudovoy yuradi. Oyliklar Toshkendagi deyarli barcha joylardan yaxshi (albatta negotiation skillga bog'liq ko'p narsa)
✔️ Hech kim ish soatni nazorat qilmaydi
✔️ Ofisdan ishlasangiz, ovqatni qisman kompensatsiya qilib berishadi
✔️ Va ko'pgina boshqa perklar
What not to expect
❎ Mazza qilib team bilan ishlash. Chunki teammatelar katta ehtimol bilan boshqa davlatda bo'ladi
❎ Team building uchun imkoniyatlar
❎ Moskva bilan vaqt farqi. Ular o’z vaqti bilan 12-1 da boshlaydi, bizda bu 2-3 degani
❎ 1-2 soat ishlab, dam olib yurish. Ishoning, ishlashga to'g'ri keladi
System Design
Interview uchun ortiqcha narsa kerak emas:
- Primerdagi hamma primerlarni ko'rib chiqsangiz va
- Alex Xuni kitobini o'qib
- tryexponentda mocklar qilsangiz more than enough
Lekin chuqurroq o'rganish uchun albatta boshqa materiallarni ham o'qish va praktikada qo'llash kerak bo'ladi. Tepadagi stagelarni qilib chiqishga 1 oy vaqtim ketdi.

Yaqinda O’zbekistonda Competitive Programming bo’yicha top-1 va eng birinchi grossmeyter bo’lgan inson bilan uchrashdim.
Timur Sitdikov — juda ham aqlli, oqko’ngil va oson aloqaga kirishuvchan inson 💚
Ohirgi marta 6 yil avval ko’rishgan edim. Bu safar ortiqcha savollar bilan qiynamaslikka harakat qildim, lekin shunga qaramay masala ishladik, ahir bizni CP birlashtiradi👀 Eng qiziq joyi, shuncha yil davomida haligacha uning jamoasidan boshqa jamoa ICPC finalga chiqa olmadi

Ikki hafta avval interviewlarga tayyorlanishni qayta boshladim. Keyingi 3 oy tayyorgarlik davri bo’ladi. Offer olsam albatta aytaman, lekin qanday tayyorlandim degan post qilmayman (tan olaylik, unaqa postlar juda ko’p).
Lekin men bilan tayyorlanishingiz mumkin. Avval coding challengelar uchun ishlatgan ushbu guruhimizda (removed the link) barcha qadamlarimni ulashib boraman. Anchagina ko’p narsalar yozishim mumkin, shuning uchun agar rostan birga shug’ullanmasangiz, yaxshisi guruhni mutega tiqing yoki qo’shilmang. Guruhga access keyin ham bo’ladi (deb umid qilaman), kerak vaqt qo’shilaverasiz.
Bu kanal offer olmagunimcha passivligicha qoladi, shuning uchun buni ham nima qilish o’zingizga havola 🙂

Google onsite interviewlarimdan feedback keldi: PASSED! YAAYYY!!!

Been silent since June.
Failed 9 interviews (including Jane Street).
Passed 1 (Google).
1 still in progress.
This week: What actually happened when I bet everything on interview prep.
Tomorrow: Why I went all-in.

Going all-in
May 2025. Yandex. The biggest tech name in Uzbekistan.
I quit.
Why leave? Simple: I'm wired different.
I chase adventure and great colleagues over comfort. Yandex had the name, the work was solid, but something was missing: the energy. the people who push you forward.
"Good enough" has never been enough for me!
Same day: Started prepping for Google.
What "all-in" meant:
- Telegram (only a few people had access)
- No side hustles (also no income)
- Rejected any offer to make a buck
- 6-8 hours daily: problem solving, system design, mock interviews, healthcare
- Day in, day out. No schedule, no weekends
One target: Google. Every other company was practice.
Jane Street caught my eye later (insane comp), but timing didn't work. Made it my next target after Google.
The result?
9 companies: mix of rejections both ways.
1 said yes (Google).
1 still deciding.
Tomorrow: $20k and 6 f*cking months of my life

$20K and 6 months
$20K… Six months… Which one hurt more? You’ll find out soon.
But first, let’s answer this question: could I have spent less? Yes! Cheaper mocks or just lock in and grind. But at what cost?
I paid for low-quality mocks at first, but quickly realized I’d get nowhere with that. Got better ones that exposed my weaknesses. $6K on mocks and mentorship. I bought truth, not comfort!
Meanwhile, life doesn’t pause. $12K on monthly expenses. And when rejections were too much? $2K on two trips to recharge. Because grinding without breaks is how you break! (wow, I like how I phrased it 😁)
I got rejected so many times that I even stopped caring about it. What I cared about was A FEW companies, the rest were just free real interviews.
Call it expensive. Call it reckless. I call it the price of not settling. You can’t imagine how much I like playing bold and risky!!!
Because I believe:
In the next few posts I’ll share the most valuable things I learned while researching and prepping for all of these companies.

Interviewlar - ko'zingizni ochadi!
Kompaniyadagi ochiq pozitsiyaga topshirdingiz. Screeningdan o'tdingiz. OA yoki phone interview, so'ng yana 3-4 ta technical. Ohirida behavioral yoki culture fit interview. Team-matching, negotiations va offer... Ehhe
100 ga yaqin kompaniyalar to'g'risida o'rganib qilgan 2 xulosam.
Har oy ofisda tekin massaj taklif qiladigan kompaniyalar borligiga ishonasizmi. Albatta, yengilik emas-ku. Offisga kelib tekinga soch oladigan barber ham yengilik emas menga endi.

100 ga yaqin kompaniyalar to'g'risida o'rganib qilgan 2 xulosam.
Kompaniyalarni 2 turga ajratdim:
1. Oylab davom etadigan suhbatlar. Technical skillarni o'rganish soft skilldan ko'ra osonligiga ishonadi.
2. "Hire quick, fire quick" asosida ishlaydi. Asosan startup yoki small va mid-sized kompaniyalar. Quick buck.
Technical skillar tez eskiradi, tugamas quvlashmachoq o'yiniga o'xshaydi. Odatda buning qiymat chegarasi bor.
Soft skills esa o'rganish qiyin va eskirishi ham qiyin.
Har oy ofisda tekin massaj taklif qiladigan kompaniyalar borligiga ishonasizmi. Albatta, yengilik emas-ku. Offisga kelib tekinga soch oladigan barber ham yengilik emas menga endi.
