Edit: this is from the perspective of a technical interviewer.
I've done around 200 or so technical interviews for mostly senior data engineering roles. I've seen every version of made up code, terrible implementation suggestion and dozens of folks with 5+ years of experience and couldn't wrote a JOIN to save their lives.
The there were a couple where the resume was obviously made up because they couldn't back up a single point and they just did not know a thing about data. They would usually talk in circles about buzzwords and Excel jaron. "They big data'd the data lake warehouse pivot hadoop in Azure Redshift." Sure, ya did, buddy.
Yes, they were "pre-screened". This was one of the BIG tech companies.
