Can anyone tell me, definitively, whether or not you're allowed to look at official sources of documentation while taking a #Hackerrank test?

I had to take one yesterday, for an SRE role. The first question was asking me how to create a container with a #Terraform provider that I'd never heard of, and didn't know the syntax for.

There's no way for us to know everything we need to do our technical professions by heart. That's so unrealistic an expectation.

Needless, to say, even with only 10 questions, I'm certain I bombed. They asked me about Java, which I've never coded in. They asked me about Typescript, which I've never coded in.

How did we get to the place where we decided that random exams with random questions (often about stuff we'll never use *on the job*!!) are a good metric to decide someone's suitability for a role???

If you ask me, it's a *TERRIBLE* metric.

So I decided to give the HackerRank test a go for Amazon... Yeah... Went as well as I thought it would... Didn't manage to get working code for either question and with 15mins to go just decided I'd had enough and closed the test ​

Story: I failed my first tech interview.

Despite having been coding for 10+ years, I froze on the live coding test and couldn't remember basic syntax.

Lesson learned: I started practicing daily on #HackerRank to build my confidence.

How do you prepare for coding interviews?

Want to ace your next coding interview?

1. Practice explaining your thought process out loud.
2. Study data structures and algorithms.
3. Practice #LeetCode and #HackerRank challenges.
4. Do mock interviews with friends.

Confidence comes from preparation.

Преобразование Уолша-Адамара

На сайте hackerrank.com есть отличная задача . По заданному массиву short[] A; найти максимальное количество его подмассивов, xor элементов которых будет одинаковым. Сам этот xor тоже нужно найти. Максимальная длина массива равна 10 5 , так что квадратичный алгоритм не укладывается в лимит по времени исполнения. Я в своё время с этой задачей не справился и сдался, решив подсмотреть авторское решение. И в этот момент я понял почему не справился - автор предлагал решать задачу через дискретное преобразование Фурье.
