I applied online on the jobs.dell.com website. The posting had no close date visible until you actually applied.

They texted on a Monday at 10 am and then called at 4 pm. I was sent questions for the data science intern position, which I didn't apply for since I was unqualified.

Then we got on a screening call, and everything went well. The recruiter talked about the perks of the company and the length of the work contract, and repeated the (correct) questions for the job posting.

Then the recruiter asked if I had any sort of experience with SQL and Python outside academic settings. I am a programmer with good grades, so I am proficient in these.

When she found out I didn't, she said I was unqualified. They really want you to have something like a course from Coursera related to the requirements of the job posting, which were Python and SQL. However, the contents of those courses are the same as those I have taken in university, which I passed with above-average grades where we used SQL a lot. I also have a project that uses Python with data structures.

So, expectations are unclear. The job posting is vague, saying "proficient in X," but they actually want a certificate from a course related to X from Coursera.

Then, to be fair, they are probably measuring everyone by the same bar, and the job posting was open to a lot of people who aren't programmers, including business people.

Have you used Python or SQL outside academic settings?

Are you proficient in English?
