Recuiter reached out to me, asked me about my background. Originally applied for software engineer II since I had over three 3 years of experiences but recuiters lower it to one because she believe I did not have enough experience with scaling enterprise level system. First interview round was with an engineer. I got asked a behavioral question follow by a leetcode hard problem afterwards. It was huge difficulty from the getgo. You really need to prep for months to have a decent shot. I grinded leetcode for just 3 weeks and got destroyed as a result.
