Four Modes. One Recurring Nightmare.
Four modes. Each one a different flavor of being asked to perform under pressure.
“Tell me about a time when you absolutely crushed it.”
“Let's keep this practical: design a distributed system for a button.”
“Our client, a $4B snack company, is losing market share to dried mango.”
“That answer was fine. Try again but this time make it good.”
People said things
Applied to 847 jobs. Got 2 callbacks. One was a scam. PrepStack got me the other one.
Marcus T.
Purdue '25
The AI asked me a harder question than Goldman did. I think Goldman lowered their bar. I did not.
Sophie L.
UIUC, Finance '24
I practiced my 'tell me about yourself' 63 times. It's now 38 seconds, hits all competencies, and I cry slightly less.
Derek O.
Alabama MBA
PrepStack's stress mode told me my answer was 'technically correct but soulless.' I've never felt so seen.
Anika R.
UIC, CS '25
I bombed the technical round anyway, but I bombed it with incredible eye contact and a firm handshake.
James W.
Cornell '25
Used the voice mode on my commute. My Uber driver said I seemed 'extremely hirable.' He gave me 5 stars.
Fatima H.
Purdue, Daniels School of Business MBA
After 14 months and 300 applications, I got an offer. PrepStack was involved in months 13 and 14. Correlation is not causation.
Ryan G.
UIUC '23
The AI told me to 'quantify my impact.' I now have a spreadsheet tracking every decision I've made since 2019.
Preethi N.
Alabama, Data Science '24
My interviewer said I seemed 'suspiciously prepared.' I took that as a compliment.
Zach M.
UIC '25
PrepStack correctly identified that I had been describing my 'team lead' role when I was actually an intern.
Laura B.
Stanford '24
I asked the AI for feedback and it said 'good start.' I have not recovered.
Ben T.
Purdue '25
Hired as a PM at a major wizarding firm. They asked me to size the market for enchanted brooms. PrepStack's case mode prepared me perfectly. The offer letter was a Howler. I accepted.
