The interview process involved a HOME-Project on predicting the price of a list and betting against others to make the most money. The final round consisted of several sections: Excel: This section was fairly easy, requiring some basic business knowledge. Machine Learning: The questions were straightforward, with nothing particularly challenging. SQL: This part focused on overall understanding rather than complex queries. Overall, the interview was easy, but I wouldn't recommend joining the company. The work environment is unpleasant, there's little room for growth, and the salary is among the lowest in the industry. Consider accepting the offer only if you have no other options.
