LinkedIn is the world’s largest professional networking platform, with over 740 million members worldwide as of October 2022. One of the key features of LinkedIn is the ability for members to list their work experience, education, skills, accomplishments and more on their profile. This allows members to showcase their professional background and connect with other professionals in their industry.
One interesting aspect of how LinkedIn handles work experience listings on member profiles is how it determines when to send out work anniversary notifications. On LinkedIn, when adding a position to your profile, you can only specify the month and year you started and ended that role – there is no option to specify the exact date. Yet LinkedIn will still send out notifications on what it calculates to be the anniversary date of when you started at that company.
This raises the question – how does LinkedIn determine on which specific day to send out work anniversary notifications, when the profile only includes month and year for that position?
In this article, we’ll explore the approaches LinkedIn may take to calculate anniversary dates, factors they may consider, and the reasoning behind sending anniversary reminders. Gaining insight into LinkedIn’s methods can help members understand when to expect notifications and how the platform handles partial data.
LinkedIn’s Motivations for Sending Anniversary Notifications
First, it’s helpful to understand why LinkedIn sends out work anniversary notifications in the first place. There are a few key reasons the platform expends resources calculating these dates:
– It’s a user-friendly feature that provides a sense of celebration and positive reinforcement on the platform. Getting a reminder of work milestones can give members a sense of pride and accomplishment in their careers.
– It helps promote engagement. By prompting members around important work events, LinkedIn drives more users to come back to the platform and interact. This boosts overall engagement metrics.
– Notifications can act as a reminder to update your profile. If the anniversary date is incorrect, it reminds you to add or modify your employment dates.
– It allows new avenues for monetization. LinkedIn could potentially add an option to send gifts or donate to charity for the anniversary notification recipient. More notifications mean more opportunities to generate revenue.
– The data provides useful analytics. Understanding users’ tenure patterns across different companies or industries gives LinkedIn valuable workforce insights.
Overall, work anniversary reminders are a win-win for LinkedIn and its members. Members get positive reinforcement while LinkedIn gains engagement and potential revenue opportunities.
Scenarios Where Only Month and Year are Available
Typically, when someone includes employment history on their LinkedIn profile, they add the month and year they started and ended each position. However, there are some scenarios where even less information is available:
– For certain older positions, the exact month or year may no longer be remembered by the member when they go to add the role to their profile. They put down the best estimate they can recall.
– The user may consider the month or year of the role to be too precise of detail to share publicly, so they intentionally only put the year.
– When importing employment history from a resume, the parsing technology may fail to pull the month, only capturing the year successfully.
– The member may manually decide to exclude the month when importing or adding employment, considering just the year sufficient and not realizing LinkedIn uses month in their anniversary calculation.
– When copying over positions from another social media profile like Facebook or Twitter, those networks may not have a month field when entering employment, so the year is all that gets carried over.
– Some users are unaware of the option to add a month, or don’t take the time to include it.
In any of these cases, LinkedIn only has the year – and in some rare cases, may just have approximate years like “2005-2008” – to work off of when determining anniversary dates.
Approaches for Date Estimation
Without an exact employment start date available, how does LinkedIn roughly estimate the day and month someone began a job, relying only on the year they joined?
Here are some methods LinkedIn’s engineering teams may employ to fill in the missing month and day when sending anniversary reminders:
Use mid-year dates: One of the simplest approaches is to estimate the middle of the year – so if you started at a company in 2017, your start date is set as July 1, 2017 for the purposes of anniversary reminders. This increases the chance that the notification is sent relatively close to the real start date, since mid-year covers the widest range. The downside is the estimate may end up quite far off for certain roles that started early or late in the year.
Factor in position and industry norms: For common entry-level roles like new graduate positions or internships, standard seasonal start times would be taken into account. For example, if someone joined an investment bank analyst program in 2015, this would typically start in July or August, rather than January. Industry norms may also apply – such as accounting jobs often starting in January after busy season ends.
Leverage AI models: As LinkedIn’s data set grows, AI models could be developed to analyze patterns in job transition times. This may reveal that software engineers tend to start new roles early in second quarter, or that teachers typically join schools in third quarter. Identifying these trends across millions of members could allow more educated guesses of start dates.
Default to first of the month: While the month remains unknown, estimating the first of that month helps standardize dates for easier processing. So an engineering job in March 2017 would default to March 1, 2017 as the proxy start date.
Rotate month assignments: For similar roles that only have the year, the platform could alternate assigning different months to reduce bias. So for one product manager who joined in 2018, the start date is set as February 2018, while for another product manager hired in 2018 the date used is September 2018.
Incorporate user feedback: If anniversary notifications are frequently shown to be inaccurate, LinkedIn can add options for users to report wrong dates. This user feedback can be incorporated to adjust algorithms. For example, if enough people indicate their 2018 hiring anniversary is incorrect by 2 months, the model can learn to shift assignments for that year.
Build in fuzziness: Given the inherent uncertainty in estimating start dates based on limited information, the algorithms can purposefully incorporate fuzziness. For instance, a random number of days +/- 15 days is added to estimated dates, so assignments vary slightly. This accounts for the natural variance.
Factors that Influence Estimation
Some additional factors likely to be considered in LinkedIn’s estimation models:
- Seniority level – More senior roles are less likely to have fixed standardized start times, as their negotiation cycle is longer. Data may reflect later start dates for executive positions.
- Company size – Larger enterprises are more likely to put new hires through lengthy onboarding. Small teams can bring people on much faster.
- Industry trends – Beyond company-specific patterns, algorithms can track industry-wide spikes in hiring months.
- Location norms – School and academic cycles in certain countries create distinct hiring seasons.
- Time period – Macroeconomic conditions shift the competitiveness of labor markets over decades, impacting typical job transition times.
- Duration at company – Longer tenures increase probability the notification month aligns with the real start month.
- Job title keywords – Words like “intern” indicate summer months, while “assistant” roles are more uniformly distributed.
Bringing in these contextual signals on top of aggregate pattern analysis allows LinkedIn to make smarter inferences in corner cases that defy the overarching trends.
Why Notifications Are Accurate for Most Members
Given the uncertainty around estimating start dates with limited information, it begs the question – why don’t more members complain about inaccurate work anniversary notifications? There are a few key reasons:
- Many members do enter their full start dates, so no estimation is needed.
- Defaulting notifications to mid-year hits close to the actual for a substantial portion of roles.
- For long tenures, the notification month often aligns with reality, even if the date is off.
- Members may not recall the exact details to recognize when a notification is slightly off.
- The notification drives positive nostalgia, so minor inaccuracies are ignored.
- Members are not sufficiently motivated to report wrong dates through feedback flows.
Essentially, the value members get from receiving any reminder of their work milestones outweighs precise date accuracy. And continuous improvements to LinkedIn’s models increase accuracy over time.
For the minority of cases where notifications are significantly off, it can appear jarring and misleading. But the majority of members enjoy the prompts enough to outweigh the friction for the few.
Best Practices for Accurate Notifications
Members who want the highest accuracy in their work anniversary notifications can follow these best practices:
- Enter full start date details when first adding positions, rather than only month and year.
- Double check dates when importing profile information from other sources.
- If you notice incorrect notifications, take the time to provide feedback to LinkedIn through their reporting flows. This improves the systems.
- If possible, validate with former managers or colleagues the exact employment dates for older roles.
- Proactively update your profile with any missing details on job transitions.
Following these steps can minimize the need for estimation and assumptions in LinkedIn’s models, leading to the highest accuracy.
The Value of Work Anniversaries
Despite some challenges in precisely calculating start dates with limited data, LinkedIn’s anniversary reminders provide a thoughtful member experience. The notifications drive positive sentiment and engagement on the platform.
For members, work anniversaries are a valuable moment for reflection. The reminders give professionals a chance to celebrate career accomplishments and progress. For employers, they surface opportunities to recognize employee loyalty and length of service.
Overall, the anniversary feature is a small but meaningful way LinkedIn adds value for its members. Understanding the considerations behind the calculations provides helpful context on the user experience.
Key Takeaways
Here are some key takeaways on how LinkedIn handles work anniversary notifications:
- Anniversary reminders drive engagement and positive sentiment, despite uncertainties in start date estimates.
- Various algorithms infer start dates based on patterns by industry, company size, job titles and other signals.
