This may have been The Pilot Episode Sanction, S01E01 of the cult classic The Middleman. In the opening scene, the main character (Wendy Watson, played by the criminally underemployed Natalie Morales) is working as a temp receptionist at "AND Industries" (motto: "We scramble your DNA".) Her desk is in front of a window onto a modern-looking white & stainless-steel laboratory, and she has her back turned to it.
However, lights start flashing in the laboratory and things quickly go wrong. Wendy does not notice anything going wrong until a genetic abomination bursts through the glass wall behind her.
This doesn't quite match all of the details you mention, but here's what does match:
a new female employee or intern in a lab setting. She seemed inexperienced ... I want to say the scene was a job interview. While the interviewer/s are conversing with the candidate, mayhem occurs either because the creatures escape and are causing mayhem, and/or because experiments on the creatures go haywire. They try to pretend like it's no big deal and try to ignore the situation, but the madness is overwhelming.
Wendy is a temp, and during the scene is talking with her mother on the phone about how "plenty of art school graduates get science jobs." However, she's not being interviewed. (She does talk to her temp coordinator in the next scene of the episode, though, so perhaps you conflated the two scenes.)
one of the creatures exploded at one time, splattering all over the glass panel.
The creature shown above doesn't explode, but rather suddenly comes out of the smore and hits the glass as something of a jump scare.
The whole scene was a static shot, focusing mainly on the female character.
The shot isn't entirely static—there are some medium shots—but the scene does return again and again to the wide-angle shot shown above.
The production might have ultimately been cancelled before release.
The show only ran for one season of 12 episodes.
I have a feeling this was some kind of sit-com.
The show was an 40-minute show (one hour with commercials), but it was undeniably comedic. Think Doctor Who or Buffy the Vampire Slayer but even more arch. The AV Club described it at the time as what you'd get "[i]f Joss Whedon and Amy Sherman-Palladino collaborated on a secret-agent/science-fiction/superhero script".
