Application and Interview Process

We are small but growing fast and we need the right people who can help us grow and retain and embed our culture and values. Our selection process is both rigorous and compassionate, but we highly encourage you to approach the journey as your authentic self. You are deciding about whether this role is for you as much as we are, so if we are a natural fit for you and you find yourself enjoying this process then you will likely thrive working at Boba. Below is an outline of what you can expect from the process, but this may change or evolve.

How To Apply

If you apply directly, please include your CV and a cover letter. Whilst your CV can cover what you have experienced, achieved, and accomplished, we really encourage you to take the opportunity to describe your personal 'why' and 'how' in your cover letter to tell us more about you as a person. e.g., Why you are interested in the role with us, and how you work with people or projects or problems, what do our purpose and values mean to you.

If you are applying through one of our recruitment partners, please share this information with them so they can brief us about you. We want to know who you are as a person and not just what you have done in the past. Applicants we think could be a good fit will be invited to Round 1 which will be done in two parts:

Round 1 – Part 1 of 2: Video Assessment

Our first stage allows us to see and hear how you communicate and allows you the opportunity to tell us a bit more about yourself than a CV or cover letter can do. Just relax and be yourself. We may throw a curveball question to you which is just to give us an idea of how you might approach a situation or scenario. We highly value cognitive diversity, so this has no right or wrong answers; please answer as your authentic self.

Round 1 - Part 2 of 2: Online Assessment

As this is an Engineering role, we will ask you to complete an online technical assessment exercise. This has been calibrated by our own teams taking this assessment to ensure it represents the strengths that a person will need to have to thrive in the role. It allows us to understand your strengths and most importantly removes a large part of the subjectivity that can enter the first stage of candidate selection and provides a consistent and level starting point for all applicants. It also significantly reduces the risk of unconscious bias at the application stage, so we can ensure each applicant has the same starting point and we can find the best talent.

The purpose of the online technical assessment is for us to learn how you solve technical coding problems in as close to a real life environment as possible.

Round 2: Getting to know each other

Approx. 2hrs with breaks. We would love to host you at our office and meet you in person, and we will pay any associated travel costs. Typical format will be:

• Meet with our Lead and Senior Trading Engineers  (Amritha & Gary) who will assign you a technical assessment exercise for about 45mins followed by a break.
• After this, one of your potential future team members will take you for a coffee/tea/beverage for an informal chat with you for up to 15mins for you to ask any questions about the role, Boba or anything else!
• Meet with our Associate Chief of Staff (Catherine) for up to 60mins

We will typically be in touch within a week on next steps after this stage.

Round 3: Final Round

Approx. 2 hours with breaks. This will be in-person in our office again, and we will pay any associated travel costs. We tollgate this stage, meaning we will make a decision on the day to proceed with the next interviewer. The structure will likely be:

•    Meet with our Chief of Staff/Chief People and Culture Officer (Iain) for up to 45mins inc. any questions you may have.

If Iain and you both wish to continue, then:

•    Meet with our COO (Marc) for up to 30mins inc. any questions you may have.

If Marc and you both wish to continue, then:

•    Meet with our CEO (Samir) for up to 30mins inc. any questions you may have.

If you have any questions about the process along the way, just ask us at

Good luck and we look forward to meeting you!
