I applied online. The process took 3 weeks.

• Phone interview - basic questions plus some easy time complexity questions.
• Take home programming project.

TLDR: Pretty unprofessional, delayed email responses. Zero feedback after giving time and effort to complete their challenge. They had sent me the challenge but outlook recognised it as spam so I didnt see it. After letting the recruiter know, she didn't give me response until 3 follow up emails and days later. She then gave me 4 days as opposed to the 7 days previously to complete it. Which was ok because it wasn't that hard. After completing challenge, which took about 4 hours - I received a 'offer' email 1 week later. The recruiter then emailed saying it was a mistake. Recruiter later emailed after 1 additional week of waiting saying I didn't make it. I asked for feedback on my code, no response.

You are given a Java/Kotlin skeleton file, although you can use any language you want so long as you describe how to run it.

The technical take-home was to read a json.line file and scan for a 10% change (+/-) in the 5-minute average of any currency pair. E.g., AUD/USD read.
