A skilled interviewer will easily recognize your strengths and weaknesses. They do not need to inquire about them, but they still do it.
Whatever their reason, you should pick some of the following strengths for your answer (in an ideal case you should actually have at least some of those strengths):
- communication skills
- ability to uncover the needs of the clients
- sales skills
- responsible personality
- attention to detail
- time management skills
- inner motivation to do the job
- true understanding of the job and the expectations of the employer
- knowledge of banking products
Say less, show more
It is better to stay humble, and mention just one or two strengths. Don’t worry, they will recognize your strengths from the way you talk and act in an interview. Humility can win you a job contract, especially if it blends with a healthy level of self confidence.
What is more, interviewers are not stupid (at least most of them know what they do :)). If you failed in a role play, you would hardly convince them of your sales skills while talking about having them. Say less, show more.
