UI/UX Design Review from Yuriy Husev
We hired DreamX to redesign our company website to better reflect DMTs modern approach to B2B lead generation and appointment-setting services. The DreamX team quickly understood our brands personality and transformed it into a sleek, fast, and conversion-focused digital experience. Their UX/UI team created user flows that made our content easier to navigate and optimized for lead capture. Communication was professional and consistent we always knew exactly what stage the project was in. The final result exceeded expectations: the new website not only strengthened our online presence but also positively impacted inbound lead quality. We highly recommend DreamX to any business looking for a creative and reliable design partner.

We worked with DreamX on developing a corporate website, and the results exceeded our expectations.
Their team demonstrated a perfect balance of creativity, technical expertise, and attention to detail.

Abhijeet Uniyal's Review Sourced from Google
Interview process was very good
Gave interview for the post of recruitment profile
First round went well
And, the lady who took my first round of interview was behaving in a very polite and convenient manner
The second was with one of the guy who told me about the company's process including it's clients and the services they are offering to the clients
And, in the end of the second round, the interviewer gave the feedback in a very positive manner that first time I have talked with you so much as I have never talked with any of the candidates before came for the interview and he really liked my confidence and my way of talking and presenting myself in the interview
The third round was with one mam who asked very relevant questions related to my education qualifications and my past experiences so far in my ex organizations
And, I also liked the behaviour of the mam who took my last round of interview because the way she was taking my interview in that manner that no one hasn't taken this type of interview before in any of the company
This organization is basically a consulting firm
And, the good thing about is that they have 5 days working policy
If you are applying for the recruiter position in this organization, make sure that you should have relevant experience in that domain and also you should focus on your communication and presentation skills because in interview, they will mostly check your communication skills only and secondly, your experience whatever the work you have done in your past organizations before
The nearest metro station to this place is Noida Sector 16 as this place is located very close to the metro station in A block itself

Frequently Asked Questions About Software Testing Companies
What services do software testing firms provide?
Software testing companies provide different testing services to identify errors, security risks, performance issues, and how the software behaves in real-life situations and across devices. As part of their software testing service, they also check if each feature works as expected, fix bugs, make improvements, and make sure new software development updates don’t break existing functions, so the software quality remains stable.Â
Hourly rates for QA testing range from $25 to $200+. The final cost is determined based on the size of the software or application, its complexity, required testing type, tech stack (custom-built and older legacy systems cost more), and niche. Â
The rate will also depend on the seniority of the software tester. Across the United States, junior quality assurance (QA) tester may charge $70 to $110 per hour, while the rate for a senior QA mentor and automation engineer can range from $130 to $200 per hour. Â
Special software testing services such as QA audit goes from $5,000 to $25,000.Â
How can businesses know what type of software testing do they need?
Businesses can determine what type of testing solutions they need based on the potential impact of failures and the likelihood of defects. Namely, if they encounter:Â Â
Core functionality issues: Use functional testing to verify features work as expectedÂ
Unstable code or new features: Use unit testing for individual components and integration testing for modules working togetherÂ
Poor system stability after updates: Seek regression testing to make sure new changes didn't break existing featuresÂ
Performance and load issues: Use performance and load testing to evaluate speed and scalabilityÂ
Security issues: Security and penetration testing are commonly used across apps handling sensitive user dataÂ
Hard-to-navigate user experience (UX): Pursue usability testing to determine how intuitive the application is for end usersÂ
Low compatibility across devices: Compatibility testing can evaluate how good the app works on different browsers, devices, and OS versionsÂ
There is also the option to choose between manual and automated testing. Â
Is automated testing more expensive than manual testing?
As an investment, automated testing is pricier than manual testing but offers a lower cost-per-test over time as it can run the same scripts repeatedly, without human intervention. Conversely, manual testing entails lower upfront fee, but its cost grows linearly as the project grows, as every test cycle requires paid hours from QA testers. Â
So, for short-term projects or ones with shifting requirements, manual testing is considered a more economical option, whereas for maintenance and regression cycles, automated testing grants better return on investment.Â
The main distinction between these methodologies is that manual testing relies on human observation and interaction to identify defects, whereas automated testing uses software scripts to compare outcomes against predicted results. Â
Manual testing is best suited for exploratory testing, usability assessments, ad-hoc bug hunting, and minor hotfix verifications where script development would be inefficient. Automated testing, on the other hand, is primarily used for regression testing to make sure the new code does not break existing features.Â
How do businesses measure the effectiveness of software testing?
The effectiveness of the software testing is measured via:Â
Code coverage: The percentage of the code that has been testedÂ
Defect density: The number of defects found per unit of codeÂ
Test case effectiveness: The percentage of test cases that identify defects; helps prune redundant and ineffective testsÂ
Time to detect and fix defects: The time it takes to identify and fix software defects and software bugsÂ
Defect leakage: The number of bugs that "escaped" to production versus those caught during the testing phase Â
