Seviyeye gore degisiyor. Senior ve Staff+ adaylarda hangi yone gidecegine dogru karar veren, bu sorudaki key problem'in ne oldugunu gorunen adaylar araniyor. Bazen hint verilebilir ama bir noktaya kadar. Konuyla hic alakasi yokken, nasil sharding yapacagini 30 dk anlatan aday, muhtemelen daha sonra bir seyleri tasarlarken de daha onem vermesi gereken konulara onem vermeyebilir gibi bir signal olarak yorumlaniyor. Yani bu her zaman soruyu soran tarafin bu iste kotu olmasi / art niyeti olmayabilir.

@grkn Kötü geçen birçok system design interview aslında adaydan değil interviewer’dan kaynaklanıyor. Aday yanlış alanda derine gidiyorsa (örn: capacity planning) yönlendirmek interviewer’ın görevi. System design bir ezber testi değil, birlikte "brainstorming" olmalı.

Bu sorular icin ucu acik, belirli bir formati yok denir ancak var. hellointerview.com/learn/system-d… buradaki adimlar ile yaklasip, sistematik bir cevap vermek gerekiyor. Interview'da neye zaman harcayaginizi da iyi kestirmeniz gerekiyor. Eger sorulan problemde en dertli olan kisim HTTP Server'ların nasil saniyede 1M request'i handle edecegi degilse, carpma bolme yapip 5000 tane server lazim diyor olmanizin zaman kaybi olmaktan baska bir etkisi yok. Ornegin, chat implement etmeniz istendiyse session management'i desiyorlar daha cok, S3 implement etmeniz istendiyse replication, sunacaginiz availability garantisi gibi konular desiliyor. Direk her kafanizda pattern match olan yere scale ettigini okudugunuz bir teknolojiyi dayamamak da gerekiyor. Heh cache olur, Redis, message queue demis Kafka diyeyim calismiyor. Neyi neden onerdiginizin teknik olarak net nedenleri olmali. Yaptiginiz trade off'lardan bahsetmeniz ve neden yapabildiginizi muglak terimler olmadan aciklayabilmeniz lazim. Problemdeki trafik pattern'lerine ve sistemi bunun etrafinda nasil tasarlayacaginiza bakmanizi da oneririm. Twitter ise mesela anlik olarak olacak spike'lar bu servis icin normal bir olay. Son olarak, ilk bakista pahali gorunuyor olsa bile hellointerview gibi servisler uzerinden mock interview yapmanizi ve feedback almanizi tavsiye ederim. Daha once bu soruyu 500 kere sormus ve insanlarin gidebilecegi her yonu gormus, girmek istediginiz sirkette yada onunla ayni domain'de calisan birisinin verecegi feedback interview'da yapacaginiz 1-2 seyi degistirip level up edilmenize bile neden olabilir.

@swissified @ulusalomer Sorular artik degisebilir. "Sirketimiz var, 10000 calisani ayni anda isten cikarip, sistemlere access'lerini kesmek istiyoruz. Bunu sirkete en az zarar vericek sekilde nasil yaparsin?" :P

@ulusalomer @grkn Tamamdır long weekend bu haftasonu, hangi gün istersen. DM den konuşalım, rol level falan ona göre bir soru seçeyim.

@swissified @ulusalomer Tabii ya, Llama ne sistem yapardi ben oradayken :P

@grkn @ulusalomer Gurkan’cım gerek yok bunlara, biz AI a veriyoruz yapıyor zaten :)

hellointerview.com/learn/system-d… bu adimlar, spesifik olarak.

@samlambert I would even pay to watch online tbh.

If we held an event where we dug deep into PlanetScale's architecture to show you why we are so resilient would you attend?

it’s in gemini, just create it in ai studio. oh, that’s for your personal google one account. for workspace you need gemini business. no, not gemini advanced, that’s ai pro now. unless you need ai ultra. oh agents? you do that in spark actually. no, not gemini api managed agents, that’s different. for coding use jules. unless you mean the agentic ide, that’s antigravity. no, that’s the old antigravity, download the new one. actually gemini cli is being deprecated, use antigravity cli. no the flash model is smarter than the pro model. unless you need pro. if it’s video, use flow. no, flow uses veo. no, nano banana is images. actually that’s in gemini now. unless you’re in search, then it’s ai mode. no, research is notebooklm. anyway it’s all very simple.

@faridmovsumov @DsMatie No photo with me 😛 Great to meet you anyways! Hope to see you again next year. Hit me up if you visit London!

I attended the Wide Event in Paris 🇫🇷 yesterday for the third time in a row, and it was, as always, amazing. It was great to see my friends from the Shopify community and to make new connections. Thanks to @DsMatie for organizing 🙏

a sequence of words that will never be said again

@fatih I dont need to shard my postgres db as it’s not that big, but since you lead the dev I will, just to experience 😬

Huge! Btw, I've also started working actively on Neki. A friend and I will be leading the Operator and Database orchestration side.

Allow data centers but only if 20% of the GPUs are set aside as “affordable” compute for low-income agents.

He just spent a year building scaffolding for his agent harness. Now release a new model update that makes all of it obsolete.

@ulusalomer Ben tasindigimda 1 bira £2.5'tu suan £7.5 oldugu yerler var. Pub'larda bu round benden gençler diyen kimse kalmadı :P

Londrada 5 yillik enflasyona bak. Nereye gitsek kurutuyoruz..

do you think, is there gonna be a clash between internal vs deployed engineers? FDE: We can turn this into an agent, with 12 custom tools and 20 mcps, each run is going to 3M tokens vs internal IT / SWEs: we actually do that with a script, deterministic, costs 0.00001$ per run 😂

@jayair Their job, actuallly, is to have said companies spent a LOT more tokens Whether or not processes are streamlined or headcount is reduced is not of interest

So AI companies are hiring loads of forward deployed engineers, which sounds like a good thing Their job though is to go into companies, streamline the processes with AI aka reduce headcount And worse, what happens to all those forward deployed engineers after they are done?

@zeeg On that note, @samlambert I would really appreciate if we were able to download the backups directly from the backups UI or able to trigger data dump from UI and download it. "pscale database dump" doesn't work for Postgres, creating creds and "pg_dump" every time is a hassle.

the great era of axing any vendor who doesnt give you your data is here

Agah Hün’ün sesi hazır formundayken dini filmlere abanalım demişler bence. Tüm dini tavsiyeli konuşmaları adamcağıza yaptırmışlar.

@SaleemUsama @GergelyOrosz Well, with that assumption then these customers who want to automate their internal processes should be able to do that with just a single prompt, why would they need FDEs?

@grkn @GergelyOrosz if swe will be solved in 5-6 years, why would you want to go back? maybe not completely solved but definitely not many engineers needed at a company reducing likelihood of job prospects regardless

I am sorry to say that the FDE roles in 2026 are ulikely to be like those in 2025. The recent FDE roles - standalone, enterprise consulting companies by OpenAI and Anthropic, standalone org unit with far lighter hiring requirements at Google - sound like SE / consultants tbh
