J'ai passé un entretien chez White Swan Data (Londres, Angleterre)
Entretien
The company is mostly quant-oriented and works on the development of mathematical/statistical models and high-performance algorithms. I had Typescript and Node questions during the interview. It wasn't that difficult but then I did not get any offer.
J'ai postulé en ligne. Le processus a pris 3 semaines. J'ai passé un entretien chez White Swan Data (Londres, Angleterre) en août 2025
Entretien
Screening Interview -> Technical Interview (More of a Architectural interview and cross questioning - on site in their office) -> Take Home exercise (Kind of scraping data from website, writing in CSV, reading that CSV and picking random record, going to website and finding that record which points to a new link and scrap data from that page into new CSV - they gave about 3-4 days to complete that task though wasnt so hard and could be completed in 1 day)
Questions d'entretien [1]
Question 1
Given a scenario that 2 data sources are there and we need to dispaly data to the customers in real time with millions of records coming in from both data sources, need to merge both perform operations and display them without delays.
