Several critics noted the song's style is comparable with the musical style of the hip hop producer DJ Mustard. In a review published by the staff of Idolator, Robbie Daw called the track worthy based on previous singles with the titular name a called it the group's "most solid single to date." In a mixed-positive review, Carl Williott initially called the track a "DJ Mustard ripoff" but complimented the group for managing to make the song "their own" with their "subtle harmonizations adding some texture", he adds. Mike Wass shared similar sentiments and called it a "sleek and sexy bop with on-trend production" and an "insidiously catchy chorus" while praising the group's musical evolution. Several publications thought it was a strong contender for song of the summer. However, other critics were not so positive. Christopher Bohlsen of Renowned for Sound gave a negative review, saying that while vocal melodies in the verses were "satisfying", the chorus just "doesn’t sound interesting enough", calling it an "utterly standard pop song". Bohlsen gave the song a two-and-a-half out of five rating.
As of 2012, estimates suggest that over fifty million U.S. workers (about 40% of the working population) could work from home at least part of the time, but in 2008 only 2.5 million employees, excluding the self-employed, considered their home to be their primary place of business. The number of employees reported to have worked from their home "on their primary job" in 2010 has been reported as 9.4 million (6.6% of the workforce), though, this number might include the self-employed. As of 2017, roughly 3.7 million employees—2.8% of the workforce—work from home at least half the time, Global Analytics Workplace reports. Very few companies employ large numbers of home-based full-time staff. The call center industry is one notable exception: several U.S. call centers employ thousands of home-based workers. For many employees, the option to work from home is available as an employee benefit but most participants only do so a fraction of the time. Top paid among work-from-home sectors are home-based physicians and radiologists in which it is suspected that they earn near the $1,975 median weekly income of physicians, as reported by the U.S. Bureau of Labor Statistics, making it a six-figure job. Studies show that at-home workers are willing to earn up to 30% less and experience heightened productivity.

Quantitative testing deals more with the factual side and statistics of a product or website, e.g. task duration, and completion rates. Qualitative testing, however, deals with the emotional side, e.g. how did the user feel, delighted, impressed, hooked or confused?
