+# HiringSolved challenge
+
+My solution to the HiringSolved challenge. If anyone from HiringSolved is
+reading this, my actual site is at <https://www.shore.co.il/blog>.
+
+1. __Math challenge__:
+
+ I did it in my head.
+
+1. __Haystack challenge__:
+
+ I googled the question and copied the answer from
+<https://puzzling.stackexchange.com/a/59513>.
+
+1. __Breadcrumbe challenge__:
+
+ For this I wrote some Python. The code is in `breadcrumbs.py` and to run it
+you need Python 3.6 and pipenv (I also use direnv for convience). To use it run
+`pipenv run ./breadcrumbs.py`.
+
+1. __Monster challenge__:
+
+ From reading the cookies from the previous challenge, I searched the DOM for
+`true` and found `true-blue`, took the color hex from there and added to the
+URL.
+
+1. __Post challenge__:
+
+ Not much of a challenge. I fiddled a bit with `curl` and posted using the
+following command:
+
+```
+curl -XPOST 'https://challenge.hiringsolved.com/REDACTED?hirable=true&name=Nimrod+Adar&email=nimrod@shore.co.il&website=https://github.com/adarnimrod/hs-challenge'
+```
