All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. {C}
It is not permissible to use Tawriyah (saying something which has more than one meaning and intending a meaning different from what the listener is likely to understand) if it results in causing others to lose their rights. Rights are not restricted to financial rights.
It appears from your question that your Tawriyah would result in deceiving your employer into believing you meet their requirements while the reality is otherwise. Hence, it is not permissible to use Tawriyah in this case.
An-Nawawi said about the legal status of Tawriyah and other ambiguous and allusive language use: "If a legitimate outweighing benefit requires deceiving the addressee or if it is an absolutely unavoidable necessity to speak falsely, then there is nothing wrong with using it, but if there is no outweighing benefit or absolute necessity, then it is disliked and not forbidden. However, if it results in taking a right unjustly or denying someone's right, then it is forbidden."
The fact that the applicants to the job are not Muslims is of no effect. What has to be taken into account is the employers themselves and you meeting their requirements and whether you are able to perform the desired job in the desired manner.
Also, fearing returning to your country if you don’t get this job does not by itself justify deceit and cheating.
Allaah Knows best.
