Hello, people, today we are streaming +- 20:00 Prague time.
Gonna talk mock interviews, DP programming, System Design, and maybe some insights about my interviews as interviewee

Ooooookay, seems like I got something, now there will be the reason for leetcode. Let's see how it goes. On top of that I would need to recall Linux internals, which is quite interesting topic.
During my prev interview at AWS, I was asked: "your server runs out of memory (disk), you deleted file, but there is still no memory, what can be the reason, and how to fix?"

π‘Wanted to share something with youπ‘ Iβve been working at Microsoft as a backend engineer for the past 3 years, with 7 years of total experience. Iβve gone through interviews at FAANG companies β including Amazon. Iβve also been on the other side, conductingβ¦
Cool, so eventually I have finished 4 mocked interviews that people wanted to try. All of the were free, and interesting for me as interviewer.
We had 2 algo/DS interviews and 2 System Design interviews.
Formal feedbacks are sent, eventually I'm done.
Thank you for this experience, hope it was helpful. I was trying to do it as close as we are doing it at Microsoft.

What I realized - I like to be interviewee MUUUUUUCH more than interviewer, idk why and how it works.
Now some interesting stuff happened on AWS side as well. So leetcode is going full flight.
Now the commitment is 3 problems per day.
Daily challenge for today:
https://leetcode.com/problems/find-minimum-time-to-reach-last-room-ii/description/?envType=daily-question&envId=2025-05-08
good to practice shortest path

On Saturday or Sunday we are streaming, btw, so we can review BST deletion, and system design.

I'm thinking about changing our System Design approach on stream to the following:
We stop implementing MVP of system design solution in C#, instead - we are doing white boarding only, and maybe code some essential parts to make sure it will work.
After that we are reviewing other's system design solutions and analyze our mistakes (OR DETECT MISTAKES OF OTHERS πππ)
I have to accelerate guys, have time until Jun. LETS GOOO
