The Benefits of Joining Bloomtech

There are 3 main benefits to joining Bloomtech online bootcamp:

  • Lambda (Bloomtech) Flexible Curriculum with live courses, online, that adjust to your schedule and learning pace. Personalized support, and on-demand learning make this learning method a true success.
  • Bloomtech Learning Process provides students with expert instructors, hands-on assignments, building products in teams, and live coding sessions.
  • Bloomtech Helps You Find a Job - A 1:1 career and technical coaching service, an outreach generator, preparation for every interview, and developing your negotiation skills for improving your compensation.

Bloomtech Entrance Exam (CCAT)

Before taking the course, Bloomtech requires taking a 15-minute exam called the CCAT (Criteria Cognitive Aptitude Test ) which will assess if you have the necessary skills to succeed in the bootcamp. 

The CCAT consists of 50 questions. The goal is to answer as many questions as possible within the 15-minute time limit.  BloomTech applicants must answer at least 23 questions correctly to proceed to the next phase of the admissions process.

The CCAT consists of three types of questions: Verbal, Math and Logic, and Spatial Reasoning.

You shouldn't be surprised if your verbal reasoning and math scores differ - most people excel at one or the other.

Also, one of the main reasons the Criteria Cognitive Aptitude test is so challenging is the time limit. The time limit is there to test your ability to solve problems under pressure. You have only 15 minutes to solve the test or only 18 seconds per question, so it is vital to practice a lot and manage your time effectively.

Bloomtech CCAT Sample Questions

Before taking the CCAT, you should "diagnose" your current situation. This will prevent you from being surprised by the test. You will know in advance if there are skills that need to be strengthened ahead of the assessment. Here are some intermediate-level sample CCAT questions for you to try:

Bloom Institute CCAT Numerical Reasoning Practice Question

A bank has two interest policies: for a monthly salary of bellow $1,500, $1.5 is charged on a monthly basis. For a salary above $1,500, $2 is charged on a monthly basis. Danny earned $1350 for the first five months of the year, and he earned $1,700 for the other seven months of the year. What was the difference in annual interest collection between Danny's pre-raise and post-raise periods?


A. 21.5$
B. 0.5$
C. 20.5$
D. 6.5$
E. 7.5$
Correct Answer
Incorrect Answer

The correct answer is (D) - $6.5

In the first 5 months of the year, Danny earned a monthly salary of $1,350, which is less than $1,500. Therefore, for each of these five months the bank charged Danny $1.5 and a total of: 5*1.5 = 5*1 + 5*0.5 = 5 + 5*(1/2) = 5 + 2.5 = $7.5.

On the other 7 months of the year, Danny earned a monthly salary of $1,700, which is more than $1,500. Therefore, for each of these 7 months the bank charged Danny $2 and a total of: 7*2 = $14.

Therefore, the difference in annual interest collection between Danny's pre-raise and post-raise periods is: 14 – 7.5 = $6.5


Bloom Institute CCAT Verbal Reasoning Practice Question



Correct Answer
Incorrect Answer

The correct answer is (C) - BLATANT is to MASKED.

REPLETE means “full with,” and FAMISHED means “very hungry.” If a person is FAMISHED, they are not REPLETE with food. In a specific context, these two adjectives directly contradict one another. 

If something is BLATANT it is very obvious, while if something is MASKED it is hidden. If something is MASKED, it is not BLATANT – these two words also directly contradict each other, and is therefore the correct answer. 

Incorrect Answers
A – SHROUD means “to cover,” and HASTEN means “to do something quickly.” These two words do not have a strong relationship.

B – PLAUSIBLE means “reasonable,” and PLACATE means “try to please.” These two words do not have a strong relationship.

D – COMMENCE means to begin, and a person GRADUATEs upon completing a course of study. Often, GRADUATION ceremonies are referred to as COMMENCEment ceremonies. These two words are related, but do not contradict one another. 

E – A person who is DEPRESSED may not be SUCCESSFUL, but these two words do not directly contradict each other. 


Bloom Institute CCAT Spatial Reasoning Practice Question

CCAT Spatial Reasoning Sample Question
Correct Answer
Incorrect Answer

Every column contains two shapes. The left column contains a triangle and a circle, the middle column contains a circle and a square, and the right column contains a square and a triangle. Down the column, one shape increases in size while another shape decreases in size.

Take a look at the right column.

The triangle becomes progressively smaller as the square becomes progressively bigger. Therefore, the answer option will have a small triangle inside of a large square. Eliminate answer option D, since it is missing a large square.

Additionally, in each row, each shape of the same size is of a different color. In the bottom row, there is a small, white circle and a small, black square. Therefore, the answer option will contain a small, gray triangle. You can eliminate answer options B and E.

Furthermore, in the bottom row, there is a large, black triangle, and a large gray, circle. Therefore, the answer option will contain a large, white square. Eliminate answer option C and you are left with answer option A as the correct answer.

The correct answer is A
