Is this a scam?

I applied earlier around 9AM to a job posting on LinkedIn for Permitting and Document Controller Officer. The job had just been posted when I applied.

I was interviewed the same day, 5-6PM. But during the interview, the role was no longer Document Controller — it became like everything: Executive Assistant, Project Coordinator, Office Engineer. Basically, everything would be done.

The interviewer said to get ready because his boss would call me after (but he didn't).

What I was asked: - Proficient in AutoCAD, construction methodology, estimating - Fluent in English, present and prepare for meetings - Supply chain, coordinate on site - Can handle the demands of the French boss

They said it was project-based, the company's first time doing this kind of project. Monday-Friday only. He didn't disclose which company. The project is said to be a Power Plant in Bicol, but I'm office-based in Makati. He said that if the boss asked me about my salary expectation, I should say 50k. Maybe the job was in demand because he said the work pressure was really high (as if nothing lasted)

I've only been in the industry for 1 year. Is this a scam?
