Vault’s Verdict

Employees at Sia laud the firm’s culture, highlighting their strong relationships with colleagues and an accessible and effective leadership team. The firm is a great place to learn on the job, although some insiders point to formal training opportunities and structured onboarding as growth opportunities. Despite rapid growth from a series of recent acquisitions, the firm remains committed to providing the flexibility, hybrid work options, and work-life balance that its employees love.

The firm uses pay bands to determine compensation at different levels, which creates stability that many employees love but also creates gripes about its compensation and bonus structures, especially for top-performing employees. In terms of diversity and inclusion, most employees say they see the firm making a genuine effort to create opportunities for traditionally underrepresented groups, but that the diversity of its top leadership has yet to catch up to that of its workforce as a whole.

From an economic perspective, the firm’s outlook is largely positive. Although some employees report that its performance is somewhat dependent on the economy as a whole, its investments in AI and reasonable pricing give it an edge as it strives to establish the same prestige in North America as it has in Europe. Under the guidance of a leadership team that has a clear vision for the future, most staff expect its growth to continue in 2025 and beyond.

 

Employee Reviews

Firm Culture

“You get out what you put in. It's a great firm that knows it has intelligent and eager people. There is no need for micromanagement, and there is not much to be found.”

“Everyone is approachable from senior leadership to people at your own level. Everyone is very helpful and supportive, and the firm is a collaborative space that is a breath of fresh air compared to the competition.”

“Sia is an innovative firm willing to engage in rapid transformations to improve its overall operations, performance, and the employee experience. However, these rapid internal transformations can be a bit bewildering at times.”

“The culture is unparalleled with support from various teams across the country, and the ability to work remotely allows for maximum flexibility and balance while still providing excellent client delivery.”

Quality of Life

“You have the flexibility to work remotely when you need to, which contributes to your overall job satisfaction and reduces stress.”

“The firm ensures a good balance between the peaks and valleys of work. For example, when a client engagement requires more hours in a given week, there’s an expectation that you’ll see fewer hours in a future week to balance it out.”

“I love the autonomy that we receive and that people genuinely care about me, but there are high expectations to contribute internally while being 100 percent billable.”

Career Development

“One of the best aspects of Sia’s career development is the chance to collaborate and learn from industry experts and leaders. However, the drawback is the lack of structure in these opportunities.”

“I’ve been offered a variety of positions across the organizations, from banking and customer experience to energy, in locations such as the U.S., France, and Hong Kong. These diverse opportunities highlight the firm’s commitment to aligning career paths with individual aspirations.”

“The firm doesn’t offer consultant 101 training. Instead, each manager offers training via engagements, which creates great exposure to senior leadership but means you learn on the fly.”

“The promotion cycle is clear, but some criteria have circumstantial requirements.”

Compensation

“The base salary is very strong, but the pay raise and bonus structures are weak.”

“One of the best aspects of the firm’s compensation package is its stability. While pay might be slightly below the market average, the company has a strong commitment to its employees and did not lay anyone off during the recent economic downturn, which helped foster loyalty and trust across the workforce.”

“The compensation package is standardized across pay bands. This means that while raises can be infrequent and there are no cost-of-living adjustments if you do get promoted to the next level, you can receive a big increase.”

“I see efforts and initiatives to ensure diversity and pay equality when determining promotions, such as a grading scale to help classify whether someone should get a promotion and by how much, however, there’s still room for growth in these areas.”

“I would prefer to have a higher match for our 401(k), which is only 4 percent right now. The new dental and vision insurance plans are also less adequate than what we had before and could be improved.”

Community Engagement/DEI

“In terms of diversity, there’s a conscious effort to create an inclusive environment, with programs that support underrepresented groups, mentorship for women, and an active commitment to diversity in hiring and promotion.”

“The firm provides generous maternity leave, and the employee representative committee organizes various wellness events throughout the year. This fosters a sense of community and encourages a healthy work-life balance.”

“The company has set up DEI units across all of its groups, with expert consultants working to disseminate best practices. Even if most of the partners are still men, I feel everyone has the same promotion opportunities and know the company is putting in a huge effort to improve its DEI policies”

“Our commitment to minimizing our environmental impact includes a goal to reach net zero emissions by 2050. Also, about 12 percent of our global revenue comes from our Consulting for Good projects, which are sustainability-centric offerings we provide to clients.”

Business Outlook

“After slower growth in 2023, our 2024 growth trended upward, and our 2025 projections look very promising. Overall, I am bullish on the firm and its leadership team.”

“We have a price tag advantage over the big four, despite having very similar capacities. We also have a history of blending consulting with AI and design, which convinces clients to trust us.”

“Although the consulting market has been slow for the last 18 months, our outlook is positive because we have grown exponentially over the past few years and acquired businesses that allow us to offer new services to our clients.”

“As a growing brand in the U.S., we have room to grow with our client solutions, but our client roster is strong, our people are committed, and our clients appreciate our work. We’re building positive brand equity every day.”

Hiring Process

“The interview and callback process is robust. Ideal candidates will have either well-rounded experiences that enable them to take on a broad range of challenges or be experts in their field who can provide world-class value to the client.”

“The firm’s interview process typically includes an initial phone or video screen, followed by several rounds of behavioral and case interviews. The final round may involve a panel interview or case presentation. The process is smooth, with feedback between rounds.”

“The hiring process values entrepreneurial, effective communicators with a growth mindset who are committed to professional development.”

“We hire candidates from prestigious educational and work backgrounds, as well as experts in specific subject areas, but strong interpersonal and problem-solving skills are always important.”

Interview Questions

“If you have a dice game that will pay you the number you roll on the dice, what price would you be willing to pay and why?”

“You have three days to evacuate 8 million residents of New York City before a bomb destroys the city. You are in charge of emergency actions and have access to all city resources. What is your plan, and will it succeed?”

“The interview process often includes a mix of behavioral and case-based questions. The behavioral questions focus on past experiences, problem-solving, and teamwork. The case interviews focus on testing analytical and problem-solving abilities, as well as business acumen.”

“For technical interviews, we ask several LeetCode-style Python and SQL problems.”
