How should I use this Civil Engineer cheat sheet?
Revise it the night before and the morning of your interview, then say each answer out loud. It covers M20 / M25, Nominal mix M20 and Slump test and more.
Is a cheat sheet enough to clear the interview?
It helps you recall facts quickly, but interviewers test how you apply them and follow up on your answers. Practise answering, not just reading.
How is this different from a list of interview questions?
A list is the same for everyone. Ambo builds your course from your resume, your target role and where you're interviewing, then writes every lesson from the interviewer's point of view: what they'll ask, a strong answer, and the follow-up they'll use to test you.
What is the certification test?
Three camera-proctored rounds that unlock one after another: an objective round, a hands-on round (coding or practical tasks for your role) and a voice interview with Ambo, who asks live follow-ups on your answers. Pass all three within 14 days to become TickBig Certified for 12 months.
Revise it, then rehearse it.
Ambo interviews you on Civil Engineer topics and follows up on what you say.
