I recently interviewed for a Large Language Model (LLM) Engineer position at ByteDance, and the experience was both intellectually stimulating and professionally enriching. The interview process was well-structured, consisting of multiple rounds that assessed my proficiency in deep learning, natural language processing, and system design specific to large-scale model training and deployment. The interviewers were highly knowledgeable and posed thoughtful questions, including those on transformer architectures, optimization strategies, and ByteDance's approach to model efficiency and scalability.

Interview
A entrevista foi toda em inglês, mesmo que a recrutadora fosse BR. Na primeira entrevista ela apenas questionou sobre experiência, qual a relação entre o seu cargo atual e o pretendido. Eu fiquei muito nervosa e infelizmente isso estragou tudo. Indico que treine mais respostas e aja com mais naturalidade.
