Airwallex Software Developer - Internship interview questions

The online assessment was neutral. It has a range of questions from the company's history, value, to Python and SQL. Also, some system design questions, probability, and brainstorming. After that you'll be invited to have a chat with a team member for 15 mins. Then is the live coding for 1 hour.

1.Phone interview - basic questions plus some easy time complexity questions. 2.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.
