EnvironmentComplex98's journey

I am currently applying for an internal entry-level service desk position at my company, where I've been employed for two years and received a promotion last year. I've been pursuing my education in the IT field, which has motivated me to seek this new role. However, I'm facing some concerns regarding my resume. I've been advised to only include the last five years of employment, which means I would need to list a previous job where I was terminated after three years. When I applied for my current position, I included that job without issue, and it didn't hinder my hiring or promotion. Still, I'm anxious that the recruiter might contact my former employer and find out about my termination, which could jeopardize my chances for this internal role. I'm unsure if my current employer will conduct background checks for past employment when considering internal candidates. Despite my worries, I have consistently received positive performance reviews in my current role as a dispatcher, which I believe has relevant similarities to the service desk position. However, I lack the higher-level certifications that many IT candidates possess and couldn't secure an internship while in school, making me doubt my competitiveness for this role.
