Go there well dress and prepare yourself very well for their questions

This doesn't answer my question at all and only mentions what I'm already aware of.

For Graduate Engineer candidates, is there a need to take any documents to the interview? The Interview Invitation and Interview Confirmation emails don't specify any required documents.

US F1 Visa Interview Transcript

Program: PhD Chemical Engineering, University of Notre Dame (Fully-funded)

Date: March-20-2024

Venue: US Consulate in Lagos

Outcome: Visa Approved ✅

Dialogue

VO: Window 3, white man with glasses and white earphones

VO: reading my I-20 I see that you're going to The University of Notre Dame du Lac (full name of University of Notre Dame) and you'll be pursuing a PhD in Chemical Engineering. And you're also fully-funded! Wow! It seems all the big brains came today! Great!

Me: cracks a smile

VO: So tell me about your research.

Me: Alright. For this PhD degree, my research will be focusing on computational catalysis....

VO: cuts in and squints eyes in curiosity Catalysis? What's that?

Me: Alright. So catalysis is the use of special substances called catalysts to expedite the rate of chemical or industrial processes and also a means of reducing their energy expenditure. This research is relevant because as a process manager at The Heineken Company, we have challenges with reducing our energy expenditure and carbon dioxide emissions.

These challenges are largely due to a technical knowledge gap not just in The Heineken Company, but in Nigeria at large. Therefore, this PhD degree will imbue me with the technical expertise I need to take on a senior process management role in energy sustainability at The Heineken Company when I return to Nigeria (return fire).

VO: That's fantastic work! Do you have a bachelor's degree sir? (Sir bawo?)

Me: Yes. I have a first-class in Petroleum and Gas Engineering from The University of Lagos.

VO: Okay. So tell me sir, focuses gaze on me, have you ever applied for a student visa?

Me: Yes, I applied for a student visa in 2020 but I did not attend the interview.

VO: VO aggressively types and scrolls through his screen while silently complaining about the network Alriiiiiighttt. VO continues this aggressive action on his laptop for 1 minute

VO: Congratulations sir. reaches for the white paper of salvation This explains bla bla bla, your I-20 is like a part of your visa, bla bla bla. It sounds like you're going on to do incredible work in The United States. I wish you the best.

Me: Thank you.

Fall 2024 is a go!😎

5 men can complete a job in 4 days. In how many days can 10 men working at 1/4 of the previous rate complete the job?

5 men do the job in 4 days at the normal rate

So, 1 man will take longer than 5 men, thus:

1 man does the job in 5*4 = 20 days at the normal rate

10 men will take shorter than 1 man, so:

10 men do the job in 20/10 = 2 days at the normal rate

10 men working the job at 1/4 the normal rate will take longer, hence:

10 men do the job in 2*4 = 8 days at 1/4 the normal rate.
