I am average. If I work hard to crack Google's interview will I have a tough time working there? I know I should worry about this after I get a offer but still asking for people's experience.
no, unless you have done literally nothing but leetcode in your career (then it will take longer to ramp up)
If you think you are average then you will never cracks their interview. Don't underestimate yourself....
Yooo
we have all levels of engineers, from mediocre to world class. so don't worry as long as you have a positive attitude, work hard and like to learn.
There is an old saying “You will never fail if you work hard” . Good luck. You will be fine.
