      The company culture is open and inclusive with great compensation and interaction.


      Lots of favoritism in the department that needs to be noted by executive leadership

        Great people! There is an incredible amount of teamwork and collaboration within teams. Dynamic environment. The company shutdowns are a huge perk! Having holiday pay for the week of the 4th of July AND the time between Xmas Eve and New Year's Day is my most favorite benefit the organization offers. It's great to take a week off and not have to come back to 2 weeks' worth of work, as compared to a normal vacation taken at any other time of the year.


        Highly matrixed environment which results in frequent communication issues and competing priorities. Collaboration across departments can be challenging due to not fully identifying the key stakeholders and/or not sharing information as freely as it should be. This results in a lot of firefighting around emergent issues, and leads to a work-life balance that is quite poor in many areas of the business. Recently, there have been cuts to benefits and multiple rounds of layoffs. The fact that there didn't appear to be any layoffs at the VP or SVP levels continues to reinforce distrust of the executive leadership team. This suggests to employees that the lower levels of the organization must pay for the poor decisions made by upper-level management.

      Interview Tips

      Feel free to post any interview questions you might be asked and I’ll help you compose an effective response :)



      Applied for a PM role with a salary range of 90-120k. Ive already told the VP my expected salary as 93k to get my foot in the door, even though I lack a college degree, prior PM experience, or designations. My previous employer paid 50k, so this would be a big salary increase. As I move into the 3rd interview round, I'm wondering if it's to consider renegotiating for 103k, despite already mentioning my expected salary as 93k. I'm concerned about the possibility of losing the offer at this stage.

      I have 5+ years of work experince and completed my Masters in Marketing. I have so many interviews, cleared the last rounds(10 companies), cracked a job interview received an offer, and decided to ghost me after that, at this point in time. I have no faith left. any tips? I have been applying since Oct 2022. Is the market going to value me or should I change my career and go into Business Analytics?

      Team interview advice? I’m on my fourth round of interviews. It’s been a weird process where the assignment I felt they were very harsh on so I feel like I’m a shaky option. I got to the last round where I meet the team. 3 interviews on zoom. It’s a global team so I’m meeting my counterparts and 1 level higher in Europe. Any questions you rec asking or points I should convey? Worried about having the same convos again since it’s back to back
