Phone interview questions were based around cv and cover letter, with general questions about why you want to work for Tessella. Face-Face interviews covered questions to test awareness of software development and data science, work already carried out and explain why it is useful and an informal lunch. You also need to prepare a 10-15 minute presentation on something that interests you and then answer questions on it from a senior member of staff. Tessella will ask for some code you have written that showcases your ability to accompany the programming task that is completed throughout the day. The task isn't hard, but they are looking to see if you are willing to ask for help and work as a team, so even if think you know the answers, asking for help is positive. This is not a lone wolf organisation.

Here is one of the questions. Split a list into two lists, called a and b. There is no joint element between a and b, and each list should contain different elements. The sum of a's elements should be bigger than the sum of b's elements. The sum of a's elements should be as big as possible while the number of a's elements should be as few as possible.
