Trinamics Software Engineer interview questions

I applied to a position through the company website but I no one from Trinamics replied. I contacted the recruiter listed in the company's job advert and she promptly replied apologizing for missing the application and invited me to go through a coding challenge for the position. I went through the coding challenge and passed it, and on the next day the recruiter sent me a meeting invitation to discuss two positions I would be well suited. A day before the meeting I reached out to the recruiter asking about the meeting, to which out of the blue she replied that the positions were already filled and I should get back to them in a few months to try again.
