It should also be pointed on that #1 is not an exclusive position on HackerRank's leaderboard. It it shared by everyone who got full points on each Java practice problem [1]. I see 16 full pages + 1 partial page = 166 people who are tied for "#1 in Java".
Furthermore, "#1 in Java" is not "Hacker Rank #1". Each leaderboard is broken up by language, topic, or contest. OP is trolling really hard here. There is no overall ranking across boards, so this claim doesn't make much sense.
(All this aside, I do really like the HackerRank platform and have been solving quite a few problems there lately.)
And HackerRank Java challenges are more like training for the beginners than a "Master of Java" verification. I know this because I also was #1 in Java and it was very easy compared to the algo challenges they have (you lose #1 position when they add new questions).
