What This Guide Is and Isn’t
This is not a list of COLREG rules. You can find those in any textbook.
This guide covers the actual selection questions — the ones that determine whether you get the offer, not the ones that test whether you’ve read the syllabus. Both types matter, but only one type is actually the reason most candidates get rejected.
Technical questions (COLREGs, cargo procedures, engine systems) vary by rank and are covered extensively elsewhere. This guide focuses on the interview dynamics — the questions most candidates prepare least for.
Cadet / GP Rating Interviews
Who’s interviewing you: HR manager + marine superintendent or senior DPA
What they’re actually assessing: Attitude, communication, physical readiness, motivation authenticity
Questions most candidates fumble:
“Why merchant navy and not some other career?” The wrong answer: “Good salary and travel” — too many candidates say this. It sounds transactional and shows no real understanding of the life. Better: “I’ve wanted this since [specific moment or reason]. I understand the lifestyle — the extended time at sea, the periods ashore, the responsibility. I’ve spoken to [officer/relative/mentor] who has done this for [X] years, and I went in with open eyes. I’m making this choice deliberately.”
“What do you know about this company?” Most cadets say nothing specific. Research the company’s fleet size, flag states they operate under, routes or cargo types. Mentioning something specific shows genuine interest.
“Are you physically prepared for sea?” They want to hear: “Yes. I can swim. I am physically fit. I passed my medical without issues. I understand the physical demands of watchkeeping and cargo operations.” Don’t hedge this. Confidence here matters.
“How will you handle being away from family for 6–9 months?” This is a psychological test. The right answer acknowledges the reality while demonstrating maturity: “I’ve thought about this seriously and discussed it with my family. We’ve prepared for it. I understand this is part of the career, not an exception to it.”
Junior Officer Interviews (Second / Third Officer, Fourth Engineer)
Who’s interviewing you: Marine superintendent + senior officer from operations
What they’re actually assessing: Competency evidence, safety culture fit, ability to function under the chief officer / chief engineer, judgment
“Walk me through your last emergency drill procedure.” They want specifics, not generic “we conducted a lifeboat drill.” What was your role? What were the deficiencies identified? What corrective action was taken? Real details from a real drill.
“Tell me about a near-miss or safety incident you were involved in.” Do not say “nothing has ever happened.” Nothing having happened means nothing has been observed and reported — this suggests poor safety awareness. Describe a real near-miss, what was done, and what was learned.
“How do you handle a disagreement with the Chief Officer/Engineer about a procedure?” The answer they want: you raise the concern professionally, document it if necessary, but understand that once an operational decision is made by the responsible officer, you execute it safely. You do not override authority, but you do not suppress legitimate safety concerns either.
“What ECDIS system have you operated? Tell me what you did when the system had a discrepancy with the paper chart.” This tests real experience vs. theoretical knowledge. If you’ve only done ECDIS in a simulator, say so and describe your simulator experience. Claiming experience you don’t have is immediately detectable and immediately fatal to your application.
Senior Officer Interviews (Chief Mate, Second Engineer)
Who’s interviewing you: Fleet manager, superintendent, sometimes the DPA
What they’re actually assessing: Management capability, commercial awareness, crisis handling, compliance mindset
“How do you manage a crew member who is performing below standard?” This is a management test. They want: clear communication of expectations first, documented warning if behavior continues, escalation to captain/chief engineer if required, compassion for personal circumstances while maintaining safety standards.
“Walk me through how you would prepare for a Port State Control inspection.” They expect you to know the specific PSC deficiency categories (ISM, SOLAS, STCW, MLC), how to prep documentation, how to brief crew, and what the consequences of a detention are for the company. Vague answers here indicate you’ve never actually run a preparation process.
“What was the most complex cargo operation you managed and what problems arose?” This is your opportunity to demonstrate real competency. Pick your best example. Have the numbers (cargo quantity, type, vessel, timeline). Describe the specific problem that arose and exactly what you did to resolve it. End with the outcome.
“How do you handle a situation where the captain gives you an instruction you believe is unsafe?” This is the most politically sensitive question at senior rank. The answer: you state your concern clearly and in writing if time allows, you make your objection known, but ultimately, if the instruction is not clearly illegal, you have a duty of care conversation — not unilateral override. If the instruction is clearly illegal (e.g., falsifying records, ignoring a clear hazard), you have a legal and ethical obligation to refuse.
Engineer-Specific Questions (MEO Class 4 / Class 2)
“Walk me through your watch handover procedure.” They want specifics — what parameters you check, what logs you verify, what running issues are communicated, what instructions are given for the watch.
“What would you do if you detected a drop in main engine lube oil pressure at sea?” Step through the diagnostic procedure. Reduce RPM first if required. Check oil levels, filters, relief valve, coolers. Alert chief engineer. Document everything. They’re looking for systematic thinking, not just the answer.
“Tell me about a machinery failure you handled during a watch.” Same as deck officers — real specifics win over textbook answers.
The Questions Every Candidate Should Prepare
Regardless of rank:
- Why this company specifically? (Research required)
- Where do you want to be in 5 years? (Show career ambition that fits their rank structure)
- What’s your biggest weakness professionally? (Honest, specific, with a genuine mitigation plan)
- What salary/contract terms are you expecting? (Know the market rate for your rank)
- When are you available to join? (Have a specific date, not “whenever”)
After the Interview
Follow up within 24 hours with a WhatsApp or email message thanking them for their time and reiterating your availability and interest. Very few candidates do this. It stands out.
