I would suggest you to look within yourself and understand why you're concerned about your intelligence. Is it because you want a good job? Tons of companies hire engineers that would fail an algorithm interview. There is a trend of simplifying interviews anyway, I think M$ is not asking algorithms or trick questions these days. Btw, I know people who failed a Google interview for 10 years. I don't think I'm very smart: I was always able to coast by academically putting the minimum effort I had to (did this until a bachelor in CS and that was it). I spent all my personal time working and starting businesses. I never bothered with companies requiring complicated interview and I'm sure I would bomb them completely; still I think I did pretty good financially (even missing out on incredibly rewarding investment opportunities). Wealth is not something you necessarily build by getting top grades, getting a top job and doing your top tech job for 10 years. Sure, that works, but there are tons of ways to get there. If you want to maximise money, knowing salaries in Russia and seeing the direction of your country, I'd recommend focusing on your spoken English, landing any job in a country with better salaries and getting a passport to move away. Then I would think more about climbing the [wealth ladder](https://nathanbarry.com/wealth-creation https://nathanbarry.com/wealth-creation) instead of passing a very hard interview. It's a though time to find a new country, EU and USA are not looking super good with all the COVID looming debt, but there are opportunities.
