Since there was no technical requirement was shared on the job posting and a good software developer can pick up any language as necessary, I told that I started to develop software with Qbasic, then I switched to Visual Basic and then I started to use C#, so even the job we are talking about doesn't require any other language knowledge now, it doesn't necessarily mean that it won't in the future or it may require completely different technical knowledge and I am one of these developers who can pick up new technologies easily.
