Trexquant Investment Global Alpha Researcher interview questions

I got the recruitment information from school . We started a phone interview two day after I applied. They asked me some programming questions about python and the related working experience. After the interview, they gave me a small project about data cleaning. Then, one day later, a following data analysis project was assigned. They are kind and patient through the whole process.

Received email from department, sent my resume and received reply in the same day. They invite me for a phone interview. It's a normal interview, my background and research experience are asked, the interviewer are their manager. He also shared me about himself and the company. Then a coding project about a game is assigned and I was asked to finish it in a week.
