Introducing Yeogieotae's Field Trainees

Yeogieotae hires field trainees twice a year, and in the second half of 2025, a total of 16 trainees gained hands-on experience across various roles including tech, sales, and HR.

Gabriel worked on AgentOps and DataOps on the DNA Center MLOps team, handling data migration from AWS Redshift to GCP BigQuery, developing the in-house agent YAPP, and automating tasks. He noted that, as much as technical skill, quick responsiveness, execution ability, and flexible thinking to validate new technologies through PoC are important.

Yoon experienced the entire sales cycle over six months on the ES Sales team, from sales support to closing actual partnerships. Performing target company selection, customer data research, cold emails and outbound calls, and partnership negotiations, she concluded that sales is fundamentally about data-driven preparation, problem-solving, and persuasive communication rather than mere talking skill.

Luka handled data mart design, Tableau visualization, and in-depth analysis on the DNA Center Business Insight team, and conducted cancellation/rebooking analysis to precisely manage Net GMV, a company-wide KPI. The analysis found that 80% of rebookings occurred within 24 hours of cancellation, and 41% of total canceled GMV was rebooked, suggesting that improving the rebooking ratio by 5 percentage points could raise Net GMV by approximately 1.7%.

Hyeoni was responsible for recruitment operations, recruitment data analysis, branding support, and Long List building on the Talent Acquisition team. By analyzing the field trainee satisfaction survey, she improved the mentor assignment and feedback system, and planned job talk sessions for trainee interaction, expanding them to 10 job functions, coming to realize that recruitment is a complex task intertwined with data analysis, branding, and campus recruiting.

All four emphasized, through the changes before and after their training, that real work is not simply performing tasks but a role that requires data, collaboration, initiative, and problem definition together. They left a message for the next field trainees to create opportunities for themselves and actively take on challenges, rather than just doing what is assigned.
