The first round was a more informal phone call. After I passed this, I was provided a technical assessment that was graded before they shared the opportunity for a final technical interview.

Costello seem to have an open job advert and it appears they are only after the very best. An extremely time consuming technical assessment which seems very other the top for an entry level role. On top of that they give very generic feedback about grammar for the written assessment which I know is not true as I made sure to be very thorough. It seems crazy to reject a candidate for grammar given grammar and AL tools are used nowadays rather than judge them on their scientific capabilities.

The interview process was smooth and straightforward, with standard questions. The team was very accommodating, professional, and welcoming, creating a comfortable environment that made the experience positive and stress-free overall.
