The Effect of Sociodemographic Factors on Obtaining a Place in Core Surgical Training.

Competition for Core Surgical Training (CST) is rising, placing a strong emphasis on interview performance. Several interview courses offer to help candidates secure their chosen surgical job but at premium fees. A group of London-based CSTs started a free course offering high-quality mock interview experiences to over 90 applicants in 2022, with the aim of providing an accessible opportunity for financially disadvantaged candidates. Course candidates completed three sets of questionnaires, pre- and post-mock interview, and a final one upon job allocation. Candidates' educational background and schooling history were obtained as well as their self-assessment score, eventual rank after interview and the rank of the job they had accepted. The three sets of questionnaires were completed by 87, 73 and 45 candidates respectively. Overall, there was a statistically significant difference in self-reported confidence scores after the course (P < 0.001). There was no significant difference in the self-assessment score of the 44.2% of candidates who had attended private education in the UK, compared to publicly educated (P = 0.0525), nor was there a difference in their rank after interviews (P = 0.236). Candidates who spent £50 or more had higher self-assessment scores (P = 0.042) but they didn't rank higher in overall scores (P = 0.591). Interview preparation courses are helpful in increasing candidates' confidence, however spending more money does not translate into a better overall interview performance. Our study suggests that candidates from private education backgrounds do not have an advantage in the CST application process.
