Marine biologists are scientists who research life in the oceans and other saltwater environments such as estuaries and wetlands. They observe and analyze data, conduct experiments, rehabilitate injured marine animals, and document the origins, behavior, genetics, and diseases of marine life.

Read the full article of Pritish Kumar Halder, in which he discusses the basics of the Marine Biologist’s Interview, with a list of topics.

Marine biologists are adaptable to live in basic living conditions in minimalist environments, working in all types of weather, and living aboard research vessels.


Employment of marine biologists is projected to grow 5 percent (for zoologists and wildlife workers) from 2020 to 2030, about as fast as the average for all occupations.


Marine Biologist’s Interview: the Basics


To ensure success, marine biologists should have meticulous attention to detail and demonstrate a keen interest in understanding and improving the marine environment and its ecosystem. Top candidates will have instinctive problem-solving skills and display confidence in practicals.

Marine Biologists typically have at least a bachelor’s degree in a closely related field like Biology, Ecology, or Zoology. Doctoral-level education in this field equips you with a comprehensive knowledge of physiological, genomic, organismic, evolutionary, and biochemical processes of saltwater organisms. In addition, it helps you understand the relationship between the organisms, their processes, and their physical and biotic environments. Ph.D. programs often allow you to take on a specialty within the field, including photobiology, deep-sea biology, vertebrate biology, high-pressure biology, or microbiology.

The level of the interview will directly depend on the experience you have, followed by your qualification and work skills. However, if the candidate is an experienced person, the process can tricky and technical to test the applicant’s true abilities.


List of Topics to Prepare


Marine biologists often work at sea as well, conducting research and observations of salt-water organisms from aboard boats or submarines. However, it is often necessary to work in a lab with access to industry-current microscopes and other technology. While the level of questions does depend on the experience of the candidate, it usually revolves around these topics:


  • Degree in marine biology or marine science or similar (essential).
  • 2 years of experience in a marine science environment.
  • Ability to plan and execute experimental protocols.
  • Excellent knowledge of microscopes, electronic equipment, dissection, collection, and preservation of biological and chemical samples.
  • Adaptable to live in basic living conditions in minimalist environments, work in all types of weather, and to live aboard research vessels.

Knowledge, skills and experience

  • Superb interpersonal skills to work with a variety of people from local fishermen and government officials to activists and professors.
  • Fantastic teamwork skills, whether working as part of a research team in a laboratory or an expedition team at sea.
  • Practical experience in scuba diving, boat handling, and first aid.
  • Analytical thinker with strong conceptual and research skills.
  • Strong numeracy and IT skills.
  • Excellent laboratory skills, such as sequencing, writing risk assessments and standard operating procedures.
  • Willingness to keep up to date with current marine information and research.
  • Conduct inventories, testing and monitoring of marine life exposed to pollutants.
  • Collect and analyze samples, and develop new theories based on this research.
  • Engage in coring techniques, geographic information systems (GIS), visual recording and sampling in order to determine the health of the marine environment.
  • Preserve specimens and samples of known and unknown species and diseases.
  • Track the distribution, ranges and/or movements of marine populations.
  • Scuba dive to survey endangered organisms and implementing preservation strategies.
  • Prepare detailed reports for agencies, funders, commercial organizations, government organizations or oil companies drilling on the seabed.
  • Communicate the latest findings on marine biology through academic publications, conferences or outreach.
  • Conduct environmental impact assessments that evaluate possible environmental impacts of proposed projects or developments.
  • Coordinate and track assignments, schedules and budgets.
  • Conduct expeditions on fishing and research vessels in polar, temperate and tropical seas.
  • Provide policymakers with the scientific information needed to best manage the marine environment and advocate this in the policy process through government liaison, press and media.

When interviewing for Marine biologist interview position, your interviewer will ask questions to assess your perform in regional knowledge and experience. The answers you give can be a deciding factor in whether you receive a job offer.
