Cleaner (Commercial) — Job Description & Salary in Germany

Vigilance beyond the cleaning task itself: the candidate describes concretely what they noticed (an open window, a dripping tap, valuables left out, a broken door) and how they reported it (to whom, how quickly, verbally or in writing). Bonus: they escalated correctly instead of improvising a fix themselves. Someone whose default attitude is 'that's not my job' shows a passivity that becomes a real risk on an unsupervised site.

Independent prioritization under time pressure: the candidate names a concrete criterion (what's visible to customers or staff, what can be pushed back) and gives the site manager a realistic update instead of agreeing to everything. Bonus: they drew a lesson from it, such as building in buffer time going forward. Someone who describes simply working faster, without mentioning quality, tends to sacrifice thoroughness for speed.

Honesty and a willingness to learn rather than glossing it over: the candidate describes the incident concretely (wrong dilution, mixing two products, slipping on a wet floor) and the specific fix (checked the safety data sheet, warned a colleague, put out a warning sign). Someone who claims they've never made a mistake or had a near-miss either has little hands-on experience or isn't being upfront about it.

Clear discretion without curiosity: the candidate closes the door, does not touch the documents, and reports the incident to the site manager or security without commenting on the content or repeating it to anyone. Someone who admits to glancing at what was there shows a trust gap that isn't acceptable given unsupervised access to premises.

A realistic rather than automatic yes: the candidate briefly assesses the scope (how many rooms, what condition), commits to what's genuinely feasible in the remaining time, and is transparent about what won't get done. Bonus: they suggest a compromise, such as focusing on visible areas and finishing the rest early the next morning. Someone who agrees to everything without checking the scope either delivers poor quality or stays late unpaid without raising it.

Willingness to raise it directly and factually rather than looking away or escalating immediately to management: the candidate speaks to the colleague first (citing the safety data sheet, skin irritation, or material damage as the reason) and only escalates if nothing changes. Someone who goes straight to management without having the conversation, or who quietly lets the behaviour slide, shows a gap in taking ownership within the team.

Concrete safety practice: gloves and, where relevant, eye protection, never mixing different products (risk of chlorine gas when mixing acid and chlorine cleaners), separate and labeled storage, checking the safety data sheet when unsure, adequate ventilation during use. Someone who can't name these points concretely either has little hands-on experience with bathroom cleaning or shows a dangerous carelessness around chemicals.

Practical differentiation rather than a one-size-fits-all method: PVC tolerates most standard cleaners, natural stone needs pH-neutral products due to acid sensitivity (marble, limestone), and carpet needs spray extraction or dry shampooing rather than wet methods depending on the soiling. Bonus: the candidate gives a concrete example of the wrong method damaging a surface. Someone who would treat every floor with the same product and method shows a lack of practical substance.

A clear grasp of the distinction: routine cleaning is the daily or several-times-weekly task (dusting, floors, restrooms, trash), while deep cleaning is the more intensive, less frequent thorough clean (carpet shampooing, machine floor stripping, window cleaning). A rough but plausible time estimate shows hands-on experience. Someone who doesn't know the difference, or gives an unrealistic time estimate, hasn't independently planned a deep clean before.

A structured start rather than diving straight in: a walkthrough of the site with the site or practice manager, clarifying hygiene standards (e.g. disinfecting contact surfaces, separate cloths per room category), building a checklist per room, and coordinating cleaning times with the practice's opening hours. Bonus: the candidate mentions colour-coded cloths or buckets to avoid cross-contamination between treatment and restroom areas. Someone who answers 'just clean it like usual' underestimates how hygiene-sensitive a medical practice is.

Diagnosis rather than defensiveness: the candidate first checks the actual condition on site, compares it against the checklist (is a step missing, is the order wrong, is the area used more heavily than planned) and talks openly with the client instead of getting defensive. Bonus: they propose an adjustment, such as a higher frequency during peak times. Someone who dismisses the complaint as unfounded without checking themselves risks losing the contract.

Practical organising skill: splitting by floor or area rather than by task type (avoids duplicated walking), accounting for different experience levels on the team (assigning more complex areas to more experienced colleagues), and building in a realistic time buffer for unexpected mess. Bonus: the candidate schedules a quick check-in halfway through. Someone who splits the work purely evenly by headcount, without considering area or complexity, shows limited practical planning experience.

Internalized rather than performative responsibility: the candidate describes that the quality of their work stays the same whether or not someone is watching, and gives a concrete example. Someone who only says in general terms that they're reliable, without an example, hasn't really answered the question.

A confident, matter-of-fact answer rather than a defensive one: the candidate names concrete professional requirements (knowledge of materials, chemical safety, time management, trustworthiness with unsupervised access) rather than just reacting emotionally. Bonus: the candidate gives an example where a lack of care had real consequences, such as a slip-and-fall or a hygiene failure. Someone who only reacts with offense, or lets the comment pass without any reflection, shows little thought about their own profession.

Realistic limits rather than unconditional availability: the candidate describes a willingness to be flexible but also states when they'll say no (personal commitments, it happening too often), and raises that openly with the site manager instead of quietly burning out. Someone who claims to always be available without limits either overestimates their own capacity or is telling the interviewer what they think is expected.
