1. Surveying Interview Questions(top 20 questions)
   
   
   
   
   Question 1. What Is Surveying?
   Answer:  Surveying is the process of analyzing and recording the characteristics of a land area span to help design a plan or map for construction.
   
   
   Question 2. What Is A Surveyor?
   Answer:  a person who examines the condition of land and buildings professionally.
   
   
   Question 3. What Is An Automatic Level?
   Answer: An Auto Level is a Professional Leveling Tool used by Contractors, Builders, Land Surveying Professionals, or the Engineer who demands accurate leveling every time.
   
   
   
   
   
   
   
   Question 4. What Is The Use Of Dumpy Level?
   Answer:  A dumpy level is a surveying tool that measures horizontal lines. It is used to determine relative height and distance among different locations. 
   
   
   Question 5. What Is A Level Staff?
   Answer :  A level staff, also called levelling rod, is a graduated wooden or aluminum rod, used with a levelling instrument to determine the difference in height between points or heights of points above a datum surface.
   
   
   Question 6. What Is A Transit level?
   Answer:   A transit level is an optical instrument, or a telescope, complete with a built-in spirit level that is mounted on a tripod. 
   
   
     Question 7. What Is A Total Station?
   Answer:  A Total Station is a modern surveying instrument that integrates an electronic theodolite with an electronic distance meter. A theodolite uses a movable telescope to measure angles in both the horizontal and vertical planes
   
   
   Question 8. How Does A Theodolite Work?
   Answer:   A theodolite works by combining optical plummets (or plumb bobs), a spirit (bubble level), and graduated circles to find vertical and horizontal angles in surveying. An optical plummet ensures the theodolite is placed as close to exactly 
   
   
   Question 9. What Is An Optical Square?
   Answer:   An optical square is a square refracting block which refracts an incident beam at an angle of 90 degrees.It can be used with an autocollimator for measuring squareness of a workpiece.
   
   
   Question 10. What Is An Edm In Surveying?
   Answer:  An electronic distance meter (EDM) is used to read slope distances from the instrument to a particular point.
   
   
     Question 12. What Is A Digital Theodolite Used For?
   Answer: In addition to measuring horizontal and vertical angles, digital theodolite 
   
   
   Question 13. What Is The Basic Principle Of Chain Surveying?
   Answer:  The main principle of chain surveying or chain triangulation is to provide a framework consist of number of well-conditioned triangles or nearly equilateral triangles. It is used to find the area of the field.
   
   
   Question 14. What Is The Chain Survey?
   Answer:  Chain survey is the simplest method of surveying. In this survey only measurements are taken in the field, and the rest work, such as plotting calculation etc. are done in the office. This is most suitable adapted to small plane areas with very few details.
   
   
   Question 15. What Is The Purpose Of Hydrographic Surveying?
   Answer :   Hydrographic survey is the science of measurement and description of features which affect maritime navigation, marine construction, dredging, offshore oil exploration/offshore oil drilling and related activities.
   
   
   Question 16. What Is A Tacheometer?
   Answer: Tacheometry, from the Greek "quick measure", is a system of rapid surveying, by which the positions, both horizontal and vertical, of points on the earth's surface relatively to one another are determined without using a chain or tape or a separate leveling instrument.
   
   
   Question 17.  Are there any areas of surveying that challenge you?
   Answer: You need to answer this question honestly. But, always make an effort to assure the hiring manager that you work well in challenging environments and see challenges as opportunities for growth.
   Question 18. What is contour line?
   Answer: A line (as on a map) connecting the points on a land surface that have the same elevation.A
   Question 19. What is contour interval?
   Answer: A contour interval in surveying is the vertical distance or the difference in the elevation between the two contour lines in a topographical map.
   Question 20. 1 yard equal to how much feet?
   Answer:  1 yard equals to 3 feet.
