I applied online. The process took one week.

The interview process was unclear, and it was not what they described to me during the first and second interviews. The reasons they provided as criticisms are quite questionable. Upon further investigation, I found that they have a monolithic system reminiscent of early 2000s applications, with no possibility of migrating to a more modern architecture. Ultimately, I wouldn't have accepted a job offer from a technologically stagnant company.

Create a Rails project where you import a set of recipes. If the user provides a list of ingredients, you should recommend which recipes can be made with the ingredients the user has. Initially, the prompt states not to worry about UX or UI, but later on, it becomes crucial for the interviewer.
