I applied online. The process took 3 months.

I wouldn't recommend this company to my worst enemy. The interview process is incredibly lengthy, and the teams seem unsure of what they are looking for. In my case, my candidacy was transferred several times from one position to another until I decided to go to another, more serious employer. The process took 3 months, which included:

• HR Screening over the phone
• 3 hours coding assessment, quite hard
• 1 interview with Tech Lead
• A 72 hours take-home assessment, with little to no guidance
• A set of interviews with different members of the team After all these interviews, they realized they didn't need to fill the position, moving me to a Data Scientist position on another team and starting this process all over again.

Guide me through a project that used unstructured datasets.
