Interview
Firstly a HackerRank challenge, it was pretty easy and finished it in 10 minutes, then I was scheduled for a Skype interview for online programming on CoderPad. The Skype interview was also not hard and solution was straight forward. Received notice from HR for onsite interview after several days. There were 4 rounds of engineer interviews during onsite, most of them were coding and fundamental questions. However getting them done nicely and fast doesn't mean they will give an offer for you, unless you could use python, ultimately the only programming language they could understand.

Interview
First I was given a fairly simple hacker rank question to be completed in 20 minutes. Then the next step was to complete a 45 minute video interview over coderpad. The first time the call was scheduled, they sent me a faulty coderpad link, so I had to reschedule it. The second time the call was scheduled, my interviewer didn't show up. Overall I don't know what it is, but terrible interview experience that just wasted my time.

Question 1
The hacker rank was a pretty easy string/json parsing question.
