Hi,

Thanks to leetcode.
I was contacted by a recruiter from facebook on linkedin, and then he asked few Big O notaion questions and was satisfied by my anwsers, as I am from Mathematics background, so even when i was out of touch from these big O topics, I was still able to recall them. then he booked an online coding test (45 minutes ) with one of their Software engineers, it was easy difficulty question from leetcode, bit of modified version. and implemented same thing for three different types of scenarios and explained to the Interviewer BIg O time complexity for my solutions and space complexity as well, in the end he asked me if I have any questions , i just asked give me some feedback to improve. he just given a short feedback and told me best of luck for other interviews as time was going beyond 45 minutes, I told him in flow, I am not giving any other interviews anywhere else and am satisfied in my current role, this interview, i have gone through this interview as it was facebook , and he told me that he means best of luck for facebook interviews, I got an idea at the end that may be I have passed and got a feedback email next day that I passed and will be attending next stage of interview, for which again i got three weeks now to prepare, I am preparing right now in the nights two to three hours daily, as I am already working so donot have much time during day time in week days to prepare. will see how it goes and will update here.

Regards,
Rupinder
