I applied online. The process took 2 weeks. I interviewed at Bottomline (Portsmouth, NH) in Sep 2019
Interview
The interview process was quick and clear. I applied online through the career site, I was contacted two days later by an internal recruiter to schedule a phone interview.
The phone interview was 20 mins of questions about my background and an overview of the role and next steps.
Then I was scheduled for a technical interview with two of the Data Science team members who I meet with over WebEx. We discussed Python, SQL, machine learning and AI. From there I was invited to a Case Study Interview with stake holders and team members. I was given the data set 5 days prior.
Then I was invited to an onsite interview where I was asked behavioral questions. At every step the team was very welcoming and asked great questions. I was disappointed to not be selected however I did receive feedback that will be helpful to apply again for future positions.
Interview questions [1]
Question 1
What is logistic regression? State an example when you have used logistic regression recently.
Question regarding basic ML, it covers logic regression, random forest, bias-variance trade off etc. HR is very nice. It has three rounds in total and it have a take-home test.
I applied online. I interviewed at Bottomline (London, England) in Oct 2024
Interview
This company pays very poorly! £39,000 for a data scientist position based in London where you would be the only data scientist in Europe (the other data scientists are in New Hampshire, USA and India). I work for a charity and make £10,000 more than that. They do provide sponsorship but the low salary wasn’t worth it for me, and they would claw back the sponsorship fees if you quit within 2 years.
Submitted application: beginning of September
Scheduled 1st round: beginning of October
1st round: call with HR and light ML/stats questions (think along the lines of define sensitivity, precision, etc.)
Take home assessment: 48 hours given to complete it. Had to do with reducing customer churn and A/B testing.
2nd round: walkthrough of the assessment with the current data scientists. It was pretty easy since my notebook was thorough and well-explained.
3rd round: interview with the head of engineering. Easy hypothetical questions to see how you would react under pressure.
Offer received: beginning of November. I eventually declined it because it didn’t sit well with me that the position paid £39,000 when American colleagues earn MORE THAN twice that amount for the same work I would be doing (not to mention, cost of living in London is comparable to New Hampshire).
Got through three rounds of interviews that too about three months for them to decide not to move forward with my application. First interview was behavioral, second one was with some upper level managers, then interviewed with current data scientist.
