What is the SoCalGas Assessment?

The Southern California Gas Company requires its job applicants to pass one of several tests before deciding whether to invite them for a face-to-face interview. These may be A Mechanical Blue Battery test, an Administrative Test—Green Battery, a Technical Red battery test, or a Clerical/Meter Reading test.

In addition to passing one of these tests, the candidate is also required to pass a personality assessment.

The Personality assessment test is designed to estimate your general aptitude in relation to the job you're applying for. It predicts whether you will engage in counterproductive behaviors such as time-wasting, fraud, and absenteeism.

The Personality Test either asks you to evaluate people’s reactions to particular situations or rank your own behavior on a scale from one to five. JobTestPrep’s personality tests offer you a great opportunity to familiarize yourself with the test’s format and learn how to create a favorable image of yourself.

After passing the personality test, you will be required to take one of the four professional tests offered by SoCalGas.

The Mechanical Test—Blue Battery

This test measures mechanical aptitude and consists of four parts, each of which focuses on applicants’ different cognitive abilities: mathematical skills, attention to detail, and understanding of mechanical principles.

Mechanical Comprehension Sample Question

A canister containing oxygen at room temperature (25°C) has a pressure gauge attached. What would happen to the pressure if the canister were to be heated?

A. Increase.
B. Decrease.
C. Uncharged.
D. Cannot say.  
Correct Answer
Incorrect Answer

The correct answer is A.

Answering this question relies on the Ideal Gas Law:


Where P =pressure, V = volume, n = number of moles of gas (amount of gas), R = Gas constant, T = temperature.

When the temperature rises, the right side of the equation increases (provided that the amount of gas in the canister remains constant).
Since the volume of the canister remains constant, the pressure must increase in order to maintain the equation.

From a more theoretical point of view, when we heat the gas, it gains energy, and its particles begin to move more rapidly inside the canister. The increase in mobility results in a greater number of collisions between the molecules and the walls of the canister, which in turn causes the pressure gauge to indicate an increase in pressure.

The Administrative Test—Green Battery

This test is offered to applicants competing for administrative positions. It consists of three parts that evaluate your reading, reasoning, and problem-solving abilities.

Reading Comprehension Sample Question

Shinto is a religion in which devotees are concerned with their local shrine rather than the religion as a whole, having a tiny shrine-altar at home. Because it is focused on the land of Japan, Shinto is clearly an ethnic religion. Therefore, Shinto is little interested in missionary work and rarely practiced outside its country of origin. It is also an unofficial national religion with shrines that draw visitors from across the country. Because ritual rather than belief is at the heart of Shinto, Japanese people don't usually think of Shinto as a religion.

What makes Shinto become local and not globally spread?

A. Missionary work.
B. Emphasis on belief.
C. Its tiny home shrines.
D. It is an ethnic religion.
Correct Answer
Incorrect Answer

The correct answer is (D).

This quote from the passage explains that Shinto is an ethnic religion that is rarely practiced outside Japan: "Because it is focused on the land of Japan, Shinto is clearly an ethnic religion.

Therefore, Shinto is little interested in missionary work and is rarely practiced outside its country of origin."

Answer (A), missionary work, is incorrect as it is the opposite of what the passage says, and answers (B) and (C) are characteristics of Shinto but are unrelated to practicing Shinto globally.

The Technical Test—Red Battery

This test is designed to evaluate job applicants’ technical skills. It is composed of four parts that measure your mechanical aptitude, symbolic reasoning, reading comprehension, and problem-solving skills.

The Clerical/Meter Reading Test—Yellow Battery

This test is taken by applicants competing for clerical, meter-reading, and customer service positions. It gauges their ability to follow the rules and code information. It also measures their language and numerical skills.

The SoCalGas Application Process

To start your application process, you need to upload your résumé and cover letter to the company’s website. After this, you will receive an invitation to take a personality test and one of SoCalGas’s professional tests: the Mechanical Test (Blue Battery), the Administrative Test (Green Battery), the Technical Test (Red Battery), or the Clerical/Meter Reader & Customer Contact Test (Yellow Battery). Which test among these four you will be required to take will depend on the position you applied for.

The SoCalGas Interview Process

A Phone Interview

Provided you passed the personality assessment and battery test successfully, you will be contacted by a hiring manager and talk on the phone about your work history and career objectives.

A Panel Interview

After this, you will be invited for an in-person interview in Los Angeles, where the company is headquartered.
As a rule, the interview at the SoCalGas is a panel interview. You will have a conversation with three or four managers representing different departments within the company.
Questions posed in the panel interview will be situational, asking you to imagine how you would behave or react to a specific situation. There will also be behavioral questions designed to assess your general aptitude for the applied role.

Depending on your prospective position, you may be asked technical questions as well. Examples of technical questions you may need to answer in the interview are as follows: “What are the variables of Bernoulli’s Equation?” and “What factors can affect the pressure of a fluid through a pipe with constant diameter?”
If you are being interviewed for the customer service representative position, you will take CSR Response Testing, during which you will listen to several pre-recorded phone calls and reply to a customer by choosing one of the six given options.

A Final Interview

Another interview may follow. This time, you will meet with a hiring manager and a vice president.
Prior to receiving a job offer, you will need to pass a criminal background check and a drug test.

SoCalGas's Interview Questions

Listed below are some of the questions SoCalGas asks during its interviews:

  • Describe a time when you had to use and improve upon any kind of data.
  • Describe a difficult situation you encountered in your work experience and how you overcame it.
