Contributing to existing studies on global circuits of knowledge and labour, this paper presents a case study of Andy - a Chinese doctoral student in the UK - and looks at his transition from higher education to later joining the labour market after returning to China through the lens of personality traits. It draws upon literature on language socialisation and sociolinguistic studies of mobility, focusing on how social actors navigate transnational higher education and the consequences on professional development in a neoliberalising market economy. It aims to investigate how (in)appropriate personhood - as manifested in recurrent personality attributes - is enacted and negotiated in specific learning contexts in Andy's trajectory and the impact on employability, with various types of data consisting of participant observation, interviews, and relevant materials. The analysis suggests that Andy has been trained to engage communicatively with academic tasks in higher education settings. However, Andy considers himself lacking certain personality variables that could align with the criteria of a "good doctoral student"depicted by the institutions, such as being independent, motivated, and self-disciplined. Andy gradually shows disorientation in an academic career, albeit finding his inadequacy to perform the desired professional personhood in a labour market that values working experience and communication skills over education certification. This process explains why sometimes the expected communicative repertories and training acquired in higher education are not transferable into valuable resources that Andy can mobilise to become employed. This paper argues that neoliberal rationality has stratifying effects on individuals primarily due to an emphasis on self-responsibility and constant improvements. In transnational higher education, certain personality traits are considered desirable and lacking such characteristics can have side effects on mobile actors like Andy, who navigate the globalising labour market through uncertainty and precarity
